[waffle] [PATCH 13/53] wgl: provide static GLES* symbols (dlsym) via opengl32.dll

[Emil Velikov]

Under Windows there is a single library that provides the basic/core
symbols for OpenGL and OpenGL ES* alike. One should attempt to use the
latter only if WGL_EXT_create_context_es{2,}_profile is supported.

We check for the extension in waffle_display_supports_context_api()
and users are strongly recommended check the function's return value.
