-Known bugs
-==========
-undefined symbol: glGenQueries
-
-	The problem here is code in libfips directly calling OpenGL
-	functions like glGenQueries but not linking against any OpenGL
-	library.
-
-	We don't want to link against any OpenGL library so that the
-	application itself can choose which OpenGL to use (and how to
-	link/load it).
-
-	The trick is to instead make these calls indirectly by first
-	calling glXGetProcAddressARB/eglGetProcAddress. There's some
-	proof-of-concept code for this in the stash-egl-lookup-fixups
-	branch, (which needs some cleaning up).
