/**
* We need to pull in the right GL headers and determine whether we are
* compiling for ES1, ES2, or desktop GL. (We allow ES1 and ES2 to both be
* supported in the same build but not ESx and desktop). We also need to know
* the platform-specific way to get extension function pointers (e.g.
* eglGetProcAddress). The port specifies this info explicitly or we will infer
* it from the GR_*_BUILD flag.
*
* To specify GL setup directly define GR_GL_CUSTOM_SETUP to 1 and define:
* GR_SUPPORT_GLDESKTOP or (GR_SUPPORT_GLES1 and/or GR_SUPPORT_GLES2) to 1
*
* if GR_SUPPORT_GLDESKTOP is 1 then provide:
* 1. The name of your GL header in GR_INCLUDE_GLDESKTOP
* 2. If necessary, the name of a file that includes extension
* definitions in GR_INCLUDE_GLDESKTOPext.
* if GR_SUPPORT_GLES1 is 1 then provide:
* 1. The name of your GL header in GR_INCLUDE_GLES1
* 2. If necessary, the name of a file that includes extension
* definitions in GR_INCLUDE_GLES1ext.
* if GR_SUPPORT_GLES2 is 1 then provide:
* 1. The name of your GL header in GR_INCLUDE_GLES2
* 2. If necessary, the name of a file that includes extension
* definitions in GR_INCLUDE_GLES2ext.
*
* Optionally, define GR_GL_FUNC to any qualifier needed on GL function
* pointer declarations (e.g. __stdcall).
*
* Define GR_GL_PROC_ADDRESS to take a gl function and produce a
* function pointer. Two examples:
* 1. Your platform doesn't require a proc address function, just take
* the address of the function:
* #define GR_GL_PROC_ADDRESS(X) &X
* 2. Your platform uses eglGetProcAddress:
* #define GR_GL_PROC_ADDRESS eglGetProcAddress(#X)
*
* Optionally define GR_GL_PROC_ADDRESS_HEADER to include any additional
* header necessary to use GR_GL_PROC_ADDRESS (e.g. <EGL/egl.h>)
*
* Alternatively, define GR_GL_CUSTOM_SETUP_HEADER (and not GR_GL_CUSTOM_SETUP)
* to a header that can be included. This file should:
* 1. Define the approprate GR_SUPPORT_GL* macro(s) to 1
* 2. Includes all necessary GL headers.
* 3. Optionally define GR_GL_FUNC.
* 4. Define GR_GL_PROC_ADDRESS.
* 5. Optionally define GR_GL_PROC_ADDRESS_HEADER
