Vladimír Vondruš	3e81fbad41	iOS-specific function pointer loader. It seems that there is no such thing as eglGetProcAddress() and thus we are able to use only functions that are defined in the ES[23]/glext.h header and no others. So, currently, the function loader internally undefs all function name macros that were defined in our flextgl.h header, then includes the Apple's glext.h header and assigns function pointers of those extensions that are defined in the header. Apple also has some minor differences in function signatures (different constness of pointer-to-pointer variables) so I had to reinterpret_cast everything. Might seem to be uglier than including glext.h directly in our code, but I made bad experience when doing so -- I want to depend on my header bugs that are consistent across all platforms instead of depending on whatever changes Apple makes in its headers. I also want to have all functions defined and not only those that are supported on iOS. Phew. Thank you, flextGL, for making it way easier than it appeared to be at first.	10 years ago

Vladimír Vondruš	c09a929b0d	Extension loading for OpenGL ES. Added EglContext, wired flextGLInit() to be called on all GLES platforms except for Emscripten and NaCl.	12 years ago
Vladimír Vondruš	9a4b7e3a32	Using flextGL instead of glLoadGen for GL extension loading. The function pointer loading is now moved to Application classes to make it possible to decide about platform-specific API at usage time, not at library compilation time. Currently it's not possible to create the Magnum context any other way than through Application classes, will solve that in next commits.	12 years ago
