Instead of using the desktop <GL/gl.h>, we properly use the OpenGL ES 3.x headers. Also, we now use GL_EXT_buffer_storage for MAP_PERSISTENT_BIT_EXT and MAP_COHERENT_BIT_EXT as the core versions are only available in desktop OpenGL 4.4. Similarly, we need GL_EXT_texture_format_BGRA8888 for GL_BGRA_EXT as GL_BGRA is desktop-only.
