font properties
### Trade library
- New @ref magnum-imageconverter "magnum-imageconverter" utility
- Initial implementation of @ref Trade::CameraData and @ref Trade::LightData
- Vertex color support in @ref Trade::MeshData2D and @ref Trade::MeshData3D
- @ref Trade::AbstractImageConverter member functions were changed to
non-`const` to make implementation of complex converter plugins possible

@ref Trade::AbstractImageConverter and @ref Audio::AbstractImporter plugin
APIs now have access to the plugin manager in order to be able to load
other plugins

images, @ref Trade::AbstractImageConverter is able to take it and then
delegate to proper function based on whether the image is commpressed or
not
- @ref Trade::AbstractImporter and all `Trade::*Data` classes now provide
member `importerState()` functions allowing the user to access
importer-specific state
- @ref magnum-distancefieldconverter "magnum-distancefieldconverter" now uses
@ref Trade::AnyImageConverter "AnyImageConverter" by default
- @ref Trade::TgaImporter "TgaImporter" sets proper @ref PixelStorage
alignment if rows are not four-byte aligned
- @ref Trade::TgaImageConverter "TgaImageConverter" now properly handles
@ref PixelStorage parameters
## Changes and improvements
- Functionality that is not available on WebGL (like debug output etc.) is
not present in WebGL builds to reduce compiled code size
- The @ref Mesh class now stores a copy of @ref Buffer instance instead of
reference, meaning that you can move your buffers freely after assigning
them to a mesh
- @ref Texture::setStorage() "*Texture::setStorage()" fallback implementation
on OpenGL ES 2.0 and WebGL 1.0 now properly translates sized texture
formats to what the drivers expect
- @ref Trade::TgaImporter "TgaImporter" and @ref Trade::TgaImageConverter "TgaImageConverter"
now consistently use RGB(A) on all platforms and don't require BGR(A) on
desktop
- Ignoring `"No errors."` message produced by GLSL compiler/linker on Intel
Windows drivers.
- @ref Texture::image() "*Texture::image()" and @ref Framebuffer::read() "*Framebuffer::read()"
now reallocate image data only if needed, for both @ref Image and
@ref BufferImage types
- R-value @ref Image "Image*" no longer restricts conversion to
@ref ImageView as it is a valid use case (for example passing output from
@ref Framebuffer::read() directly to @ref Trade::AbstractImageConverter::exportToFile())
- It's no longer possible to call @ref Image::data() "Image*::data()" on
r-value instances as that would cause accessing freed data. Use
@ref Image::release() instead.
- @ref Buffer::map() now returns @ref Corrade::Containers::ArrayView instead
of a plain pointer for better security
- Graceful handling of broken GL contexts
- Behavior of @ref Version::GLES200 and upwards on desktop OpenGL is changed
to request an ES dialect of GLSL when used in @ref Shader (instead of a
particular desktop GL version that supports given ES version), looks for
@extension{ARB,ES2_compatibility} and others (instead of checking for a
particular desktop GL version that supports given ES version)
- Binding some default VAO in case the engine is running on core profile with
@extension{ARB,vertex_array_object} disabled
- It's now possible to create @ref ImageView with `nullptr` data (for example
for old-style texture allocation using @ref Texture::setImage())
- Various workarounds to make the engine working better on SVGA3D drivers
(VMWare guest)
### Math library
- @ref Double types are no longer restricted to just desktop GL builds, all
related types also work on ES and WebGL builds
- Default-constructed @ref Color4 has zero alpha now instead of fully opaque
black
- Proper implementation of @ref Math::Vector::isZero() for integers
- @ref Math::Matrix4::transformPoint() now properly uses the perspective
divide from projection matrices
- Updated @ref Math::TypeTraits fuzzy comparison epsilon values for
`long double` and `double`
- @ref Math::Matrix4::perspectiveProjection() now supports infinite far plane
- @ref Math::pow() now works for both vectors and scalars
- @ref Math::Vector::minmax() now works on arbitrary vectors instead of just
@ref Math::Vector2
### Platform library
- Requesting core OpenGL context by default in @ref Platform::WindowlessGlxApplication
and @ref Platform::Sdl2Application. On binary NVidia, AMD and Windows Intel
drivers this causes the context to be stuck on OpenGL 3.1, in which case
the context is destroyed and old-style forward-compatible context is
requested instead.
- @ref Platform::Sdl2Application now leaves windows positioning on the system
instead of forcing the window to be centered
- @ref Platform::Sdl2Application now shows the window only once the GL
context is fully created to avoid flickering
### Shaders library
- @ref Shaders::Flat now sets default color to white only in textured version
- @ref Shaders::Phong gained the ability to have both color and texture
- @ref Shaders::Phong is now able to do alpha-masking
## Build system
- Continuous testing for Linux, macOS, Windows MSVC, Windows MinGW, Windows RT,
iOS, Android and Emscripten on [Travis CI](https://travis-ci.org/mosra/magnum)
and [AppVeyor CI](https://ci.appveyor.com/project/mosra/magnum), with code
coverage on [coveralls.io](https://coveralls.io/github/mosra/magnum);
replacing the unmaintained and outdated Jenkins configuration
- Support for CMake subprojects. You can now clone Magnum into a subdirectory
in your project and add it using `add_subdirectory()`. The `find_package()`
command will then use the CMake subproject instead of looking for it in
system-wide locations.
- Reworked CMake buildsystem to use the new imported target workflow, see
@ref cmake for more information
- CMake targets are now organized in folders for better development
experience in IDEs such as Visual Studio or Xcode
- Added @ref building-packages-brew "Homebrew package"
- Improvements and dependency updates to the
@ref building-packages-deb "Debian package"
- Ability to build OpenGL tests also on Windows and macOS (see `BUILD_GL_TESTS`
@ref building-features "CMake option")
- Ability to override the implicit plugin directory using a
`MAGNUM_PLUGINS_DIR` CMake cache variable
- Ability to override deploy directory (used for example by Emscripten) using
a `MAGNUM_DEPLOY_PREFIX` CMake cache variable
- Better handling of compiled-in resources in static build. You don't need to
manually register resources when using Shaders library in static builds.
- `MACOSX_RPATH` is now enabled by default on CMake 3.0+
- Enabling only C++ in CMake `project()` call, if possible, to speed up
initial CMake run
- Windowless application libraries now make use of the `BUILD_STATIC_PIC`
@ref cmake "CMake option"
- Fixed `FindSDL2.cmake` module to work out-of-the-box on Windows and macOS
- Bundling a patched version of `FindOpenAL.cmake` to make it working on
Emscripten
## Bug fixes
- Wrapping mode for @ref CubeMapTexture is now correctly two-dimensional
instead of three-dimensional, wrapping mode for @ref Texture2DArray "TextureNDArray"
is now correctly N-dimensional instead of N+1
- Fixed WebGL context creation on Internet Explorer, it claims to have
version 0.94

- Fixed @ref TextureTools::distanceField() on 3.0 &lt;= GL < 3.2
- Fixed driver crash on AMD with @ref TextureTools::distanceField()
- @ref Framebuffer::attachCubeMapTexture() incorrectly behaved as a layered
attachment
- Fixed object label queries using the @extension{EXT,debug_label}
extension
- @extension{EXT,direct_state_access} function was accidentally used in
@extension{ARB,direct_state_access} code path, causing crashes on Mesa
- Properly export @ref Framebuffer::DrawAttachment to avoid linker failures
on Windows
- On Emscripten, @ref Platform::Sdl2Application was by default rendering a
800x600 canvas to an area of 640x480 pixels, causing severe aliasing.
Canvas is now by default sized to 640x480 to match the default CSS style.
- @ref Platform::WindowlessWglApplication is fixed to allow the GL context to
be created and destroyed multiple times during application run
- @ref SceneGraph::Camera now works properly with @ref Double underlying type

- Removed deprecated `Context::Flag::Robustness` enum value, use
@ref Context::Flag::RobustAccess instead
- Removed deprecated `Texture::Target` enum, use dedicated @ref Texture,
@ref TextureArray, @ref RectangleTexture and @ref MultisampleTexture
classes instead
- Removed deprecated @ref Resource conversion operator, use explicit
conversion instead
- Removed deprecated `Framebuffer::attachTexture*D()` overloads, use one of
@ref Framebuffer::attachTexture() or @ref Framebuffer::attachTextureLayer()
overloads instead.
- Removed `SceneGraph::Camera3D::near()` and `SceneGraph::Camera3D::far()`
getters, because they can't be provided anymore with current more general
implementation. THe user is advised to cache the values on application side
if they are really needed.
- Removed `AbstractImage` class and `Magnum/AbstractImage.h` header, its
functionality is present in the @ref Image "Image*" classes directly
- Removed `Image::dataSize()` function as it has ambiguous meaning in regards
to recently added features, use @ref Image::dataProperties() "Image::dataProperties()"
instead
## Performance improvements
- Reduced size of and number of allocations in @ref Mesh class.
## Documentation
- Explicit list of extensions that are available in WebGL builds
- New page explaining @ref opengl-wrapping "OpenGL wrapper layer"
- Documented extra CMake modules in @ref cmake-modules
