Lightweight Java Game Library Code

Added java debug output to linux display.c

More linux fixes

*** empty log message ***

Linux: Improve input latency by processing X messages from nPoll and nRead

Linux: improve cursor position handling (warp behaviour)

Linux: Implemented support for Extended Window Manager Hints. LWJGL now cooperates
much better with the window manager, if the X randr and EWMH extensions are supported.
Especially fullscreen handling has improved, by avoiding the use of the override_redirect
flag.

Win32 part of fast Pbuffer

Implemented new type of Pbuffer that use the Display context, which is faster than a separate context (Linux)

Fix indentation

Move native stub initialization from extgl into GLContext.java. Makes it much easier to
exlude extensions classes. Furthermore, GLContext.useContext(null) can now be used to
reset the native stubs when no context is current.
