Patch that solves the issue.
When compiling cairo with the gl backend enabled on windows with mingw-w64 I
get undefined references to glActiveTexture and glBlendFuncSeparate as the
opengl32 library only exposes OpenGL 1.1 entry points.
I attached a patch that queries the two entry points via the GetProcAddress
mechanism in cairo-gl-dispatcher.c instead. The patch works against
cairo-1.12.16 and the current git version.</pre>
