/*
PsychToolbox3/Source/Linux/Screen/PsychWindowGlue.h
PLATFORMS:
This is the Linux/X11 version only.
AUTHORS:
Mario Kleiner mk mario.kleiner.de@gmail.com
HISTORY:
2/20/06 mk Created - Derived from Windows version.
DESCRIPTION:
Functions in this file comprise an abstraction layer for probing and controlling window state, except for window content.
Each C function which implements a particular Screen subcommand should be platform neutral. For example, the source to SCREENPixelSizes()
should be platform-neutral, despite that the calls in OS X and Linux to detect available pixel sizes are different. The platform
specificity is abstracted out in C files which end it "Glue", for example PsychScreenGlue, PsychWindowGlue, PsychWindowTextClue.
