Note this file contains function definitions, so it must be compiled into
the final binary exactly once. Each platform specific implementation file
including it once should achieve this.

+ If you are copying the pugl code into your source tree, the following

+
+ PUGL_GRAB_FOCUS: Work around reparent keyboard issues by grabbing focus.
+ PUGL_VERBOSE: Print GL information to console.
