Split the OpenGL layer out, pt 9: generic pixel formats. This is quite big, so: * There are new Magnum::PixelFormat and Magnum::CompressedPixelFormat enums, which contain generic API-independent formats. In particular, PixelFormat replaces GL::PixelFormat and GL::PixelType with a single value. * There's GL::pixelFormat(), GL::pixelType(), GL::compressedPixelFormat() to convert the generic enums to GL-specific. The mapping is only in one direction, done with a lookup table (generic enums are indices to that table). * GL classes taking the formats directly (such as GL::BufferImage) have overloads that take both the GL-specific and generic format. * The generic Image, CompressedImage, ImageView, CompressedImageView, and Trade::ImageData classes now accept the generic formats first-class. However, it's also possible to store an implementation-specific value to cover cases where a generic format enum doesn't have support for a particular format. This is done by wrapping the value using pixelFormatWrap() or compressedPixelFormatWrap(). Particular GPU APIs then assume it's their implementation-specific value and extract the value back using pixelFormatUnwrap() or compressedPixelFormatUnwrap(). There's also an isPixelFormatImplementationSpecific() and isCompressedPixelFormatImplementationSpecific() that distinguishes these values. * Many operations need pixel size and in order to have it even for implementation-specific formats, a corresponding pixelSize() overload is found via ADL on construction and the calculated size stored along the format. Previously the pixel size was only calculated on demand, but that's not possible now. In case such overload is not available, it's possible to pass pixel size manually as well. * In order to support the GL format+type pair, Image, ImageView and Trade::ImageData, there's now an additional untyped formatExtra() field that holds the second value. * The CompressedPixelStorage class is now unconditionally available on all targets, including OpenGL ES and WebGL. However, on OpenGL ES the GL APIs expect that it's all at default values. I attempted to preserve backwards compatibility as much as possible: * The PixelFormat and CompressedPixelFormat enum now contains generic API-independent values. The GL-specific formats are present there, but marked as deprecated. Use either the generic values or GL::PixelFormat (togehter with GL::PixelType) and GL::CompressedPixelFormat instead. There's a lot of ugliness caused by this, but seems to work well. * *Image::type() functions are deprecated as they were too GL-specific. Use formatExtra() and cast it to GL::PixelType instead. * Image constructors take templated format or format+extra arguments, so passing GL-specific values to them should still work.

Use Corrade String[View] in some ConfigurationValue specializations. These headers are included quite often and because <Corrade/Utility/StlForwardString.h> expands to the whole <string>, it has quite a significant impact. Other cases like Math/ConfigurationValue.h are not changed at the moment, as that header is only included together with Utility::Arguments or Utility::Configuration -- and these classes are still STL-heavy, so avoiding std::string usage in just the ConfigurationValue specializations doesn't help anything at the moment.

namespace Magnum {
Rename pixelSize() and other helpers to pixelFormatSize() etc. For consistency with how VertexFormat and other enum helpers are named. The compressedBlockSize() and compressedBlockDataSize() is also renamed to compressedPixelFormatBlockSize() and compressedPixelFormatBlockDataSize(). While backwards compatibility aliases are in place, a breaking change is that Image classes now look for pixelFormatSize() instead of pixelSize(). This is used e.g. when passing GL::PixelFormat / GL::PixelType to the image classes, instead of the generic PixelFormat. While useful, it's unlikely that any project was defining their own pixel format enum and pixelSize() for a D3D or Metal renderer or whatnot, so the breakage should have no practical impact.

Prefer CORRADE_TARGET_* instead of __GNUC__, __clang__ and _MSVC_VER. While branching on a compiler is rather common, checking a particular compiler version should be needed only rarely. Thus minimize use of such macros to make them easier to grep for.

Prefer CORRADE_TARGET_* instead of __GNUC__, __clang__ and _MSVC_VER. While branching on a compiler is rather common, checking a particular compiler version should be needed only rarely. Thus minimize use of such macros to make them easier to grep for.

Rename pixelSize() and other helpers to pixelFormatSize() etc. For consistency with how VertexFormat and other enum helpers are named. The compressedBlockSize() and compressedBlockDataSize() is also renamed to compressedPixelFormatBlockSize() and compressedPixelFormatBlockDataSize(). While backwards compatibility aliases are in place, a breaking change is that Image classes now look for pixelFormatSize() instead of pixelSize(). This is used e.g. when passing GL::PixelFormat / GL::PixelType to the image classes, instead of the generic PixelFormat. While useful, it's unlikely that any project was defining their own pixel format enum and pixelSize() for a D3D or Metal renderer or whatnot, so the breakage should have no practical impact.

Split the OpenGL layer out, pt 9: generic pixel formats. This is quite big, so: * There are new Magnum::PixelFormat and Magnum::CompressedPixelFormat enums, which contain generic API-independent formats. In particular, PixelFormat replaces GL::PixelFormat and GL::PixelType with a single value. * There's GL::pixelFormat(), GL::pixelType(), GL::compressedPixelFormat() to convert the generic enums to GL-specific. The mapping is only in one direction, done with a lookup table (generic enums are indices to that table). * GL classes taking the formats directly (such as GL::BufferImage) have overloads that take both the GL-specific and generic format. * The generic Image, CompressedImage, ImageView, CompressedImageView, and Trade::ImageData classes now accept the generic formats first-class. However, it's also possible to store an implementation-specific value to cover cases where a generic format enum doesn't have support for a particular format. This is done by wrapping the value using pixelFormatWrap() or compressedPixelFormatWrap(). Particular GPU APIs then assume it's their implementation-specific value and extract the value back using pixelFormatUnwrap() or compressedPixelFormatUnwrap(). There's also an isPixelFormatImplementationSpecific() and isCompressedPixelFormatImplementationSpecific() that distinguishes these values. * Many operations need pixel size and in order to have it even for implementation-specific formats, a corresponding pixelSize() overload is found via ADL on construction and the calculated size stored along the format. Previously the pixel size was only calculated on demand, but that's not possible now. In case such overload is not available, it's possible to pass pixel size manually as well. * In order to support the GL format+type pair, Image, ImageView and Trade::ImageData, there's now an additional untyped formatExtra() field that holds the second value. * The CompressedPixelStorage class is now unconditionally available on all targets, including OpenGL ES and WebGL. However, on OpenGL ES the GL APIs expect that it's all at default values. I attempted to preserve backwards compatibility as much as possible: * The PixelFormat and CompressedPixelFormat enum now contains generic API-independent values. The GL-specific formats are present there, but marked as deprecated. Use either the generic values or GL::PixelFormat (togehter with GL::PixelType) and GL::CompressedPixelFormat instead. There's a lot of ugliness caused by this, but seems to work well. * *Image::type() functions are deprecated as they were too GL-specific. Use formatExtra() and cast it to GL::PixelType instead. * Image constructors take templated format or format+extra arguments, so passing GL-specific values to them should still work.

This is quite big, so: * There are new Magnum::PixelFormat and Magnum::CompressedPixelFormat enums, which contain generic API-independent formats. In particular, PixelFormat replaces GL::PixelFormat and GL::PixelType with a single value. * There's GL::pixelFormat(), GL::pixelType(), GL::compressedPixelFormat() to convert the generic enums to GL-specific. The mapping is only in one direction, done with a lookup table (generic enums are indices to that table). * GL classes taking the formats directly (such as GL::BufferImage) have overloads that take both the GL-specific and generic format. * The generic Image, CompressedImage, ImageView, CompressedImageView, and Trade::ImageData classes now accept the generic formats first-class. However, it's also possible to store an implementation-specific value to cover cases where a generic format enum doesn't have support for a particular format. This is done by wrapping the value using pixelFormatWrap() or compressedPixelFormatWrap(). Particular GPU APIs then assume it's their implementation-specific value and extract the value back using pixelFormatUnwrap() or compressedPixelFormatUnwrap(). There's also an isPixelFormatImplementationSpecific() and isCompressedPixelFormatImplementationSpecific() that distinguishes these values. * Many operations need pixel size and in order to have it even for implementation-specific formats, a corresponding pixelSize() overload is found via ADL on construction and the calculated size stored along the format. Previously the pixel size was only calculated on demand, but that's not possible now. In case such overload is not available, it's possible to pass pixel size manually as well. * In order to support the GL format+type pair, Image, ImageView and Trade::ImageData, there's now an additional untyped formatExtra() field that holds the second value. * The CompressedPixelStorage class is now unconditionally available on all targets, including OpenGL ES and WebGL. However, on OpenGL ES the GL APIs expect that it's all at default values. I attempted to preserve backwards compatibility as much as possible: * The PixelFormat and CompressedPixelFormat enum now contains generic API-independent values. The GL-specific formats are present there, but marked as deprecated. Use either the generic values or GL::PixelFormat (togehter with GL::PixelType) and GL::CompressedPixelFormat instead. There's a lot of ugliness caused by this, but seems to work well. * *Image::type() functions are deprecated as they were too GL-specific. Use formatExtra() and cast it to GL::PixelType instead. * Image constructors take templated format or format+extra arguments, so passing GL-specific values to them should still work.

Split the OpenGL layer out, pt 9: generic pixel formats. This is quite big, so: * There are new Magnum::PixelFormat and Magnum::CompressedPixelFormat enums, which contain generic API-independent formats. In particular, PixelFormat replaces GL::PixelFormat and GL::PixelType with a single value. * There's GL::pixelFormat(), GL::pixelType(), GL::compressedPixelFormat() to convert the generic enums to GL-specific. The mapping is only in one direction, done with a lookup table (generic enums are indices to that table). * GL classes taking the formats directly (such as GL::BufferImage) have overloads that take both the GL-specific and generic format. * The generic Image, CompressedImage, ImageView, CompressedImageView, and Trade::ImageData classes now accept the generic formats first-class. However, it's also possible to store an implementation-specific value to cover cases where a generic format enum doesn't have support for a particular format. This is done by wrapping the value using pixelFormatWrap() or compressedPixelFormatWrap(). Particular GPU APIs then assume it's their implementation-specific value and extract the value back using pixelFormatUnwrap() or compressedPixelFormatUnwrap(). There's also an isPixelFormatImplementationSpecific() and isCompressedPixelFormatImplementationSpecific() that distinguishes these values. * Many operations need pixel size and in order to have it even for implementation-specific formats, a corresponding pixelSize() overload is found via ADL on construction and the calculated size stored along the format. Previously the pixel size was only calculated on demand, but that's not possible now. In case such overload is not available, it's possible to pass pixel size manually as well. * In order to support the GL format+type pair, Image, ImageView and Trade::ImageData, there's now an additional untyped formatExtra() field that holds the second value. * The CompressedPixelStorage class is now unconditionally available on all targets, including OpenGL ES and WebGL. However, on OpenGL ES the GL APIs expect that it's all at default values. I attempted to preserve backwards compatibility as much as possible: * The PixelFormat and CompressedPixelFormat enum now contains generic API-independent values. The GL-specific formats are present there, but marked as deprecated. Use either the generic values or GL::PixelFormat (togehter with GL::PixelType) and GL::CompressedPixelFormat instead. There's a lot of ugliness caused by this, but seems to work well. * *Image::type() functions are deprecated as they were too GL-specific. Use formatExtra() and cast it to GL::PixelType instead. * Image constructors take templated format or format+extra arguments, so passing GL-specific values to them should still work.

Debug& operator<<(Debug& debug, const CompressedPixelFormat value) {
Packed debug output for enums used by Trade. Again not publicly documented because I don't like the naming and I don't have the full behavior and interactions figured out yet -- i.e., an array of VertexFormats would be printed with Debug::packed as a long string of characters without any whitespace. Not good, thus this feature probably needs to be split in two, with this being named "compact" or something else.
