Subject: [PATCH] eglwrap: Add comment describing why we don't lookup into
libGLESv2.so
A user recently asked me why we didn't perform lookups in
libGLESv2.so, (instead of just libEGL.so). I actually made the mistake
of writing code to do that before I realized the answer.
Adding the answer in a comment here should help me avoid making that
mistake again.
