/*
PsychToolbox3/Source/Linux/Screen/PsychWindowTextGlue.c
PLATFORMS:
This is the Linux version.
AUTHORS:
Allen Ingling awi Allen.Ingling@nyu.edu
Mario Kleiner mk mario.kleiner@tuebingen.mpg.de
HISTORY:
11/18/03 awi Wrote it
2/20/05 mk Ported to Linux. Derived from Windows version.
DESCRIPTION:
NOTES:
TO DO:
Some of this stuff looks platform neutral so we should consider moving that part of it outside of the the glue layer which is
only for functions which abstract up platform-specific calls into platform neutral calls invoked by Screen subcommands.
