Vladimír Vondruš	655c9ea2cf	Export GLLoadGen symbols so they can be used in shared libraries. Caused linker problems mainly on Windows, where every symbol would need to be exported manually, on Linux this was done implicitly (or with `-fvisibility=default`). I now maintain glLoadGen fork at https://github.com/mosra/glloadgen.git containing changes needed for Magnum. The `ogl_*()` functions are used only internally, various global variables for extension queries are not used at all and thus they don't need to be exported. I thus enabled `-fvisibility=hidden`. Fixes #16.	13 years ago
Vladimír Vondruš	519f9f7c32	Use glLoadGen instead of GLEW. Removed all known GLEW workarounds, added one small workaround for missing ARB_texture_compression_bptc. I didn't want to patch glLoadGen for just four enum values, this way it's possible to use stock one without any patching (except for missing OpenGL 2.1 support, as stated in external/OpenGL/GL/README.md). As one file now replaces both `glew.h` and `glcorearb.h` and it has the same size as `glcorearb.h` alone , it saves approximately 18k LOC, resulting in 15 second shorter compilation time (5:03 before, 4:48 now). Not bad.	13 years ago
Vladimír Vondruš	8f37ebe9cf	Better usage of external OpenGL headers. Moved them to `OpenGL/` subdirectory, allowing them to be included explicitly with e.g. <OpenGL/GLES2/gl2ext.h> overriding the system <GLES2/gl2ext.h> header. Our versions of the headers are thus now explicitly included in `OpenGL.h`, but they can be also included using no-prefix path if no system version is available. It might break some ES platforms, they will be fixed when found. The headers are now installed into `Magnum/OpenGL` (not into any artificial `external` directory). Now also installing GLES2 headers for OpenGL ES 2 (previously ES3 headers were installed for both ES2 and ES3).	13 years ago
Vladimír Vondruš	a0b83edd2b	Relicensing to MIT/Expat license, part 4: CMake and documentation files. They didn't contain license header before, but I think adding it also there wouldn't do any harm. Documentation is also integral part of the codebase.	13 years ago
Vladimír Vondruš	e378195d20	Added headers for OpenGL 4.3 and OpenGL ES 3.0.	14 years ago
