Subject: [PATCH] Add missing functions and bring back OpenGL
This patch adds missing functions:
IconifyWindow
GetWMInfo
GL_LoadLibrary
GL_GetProcAddress
GL_GetAttribute
GL_MakeCurrent
Adding GL_* functions brings back working OpenGL in SDL for BeOS :).
With addd GL_* functions there are few changes in Window class to handle
changes better.
Patch also fixes bug which freezed window when using MesaGL instead of
BeOS r5 GL - it just needed Window->Quit() added into BE_VideoQuit().
THX to Michael Weirauch (a.k.a emwe) who worked on that bug before and
found that it freezes because of lock somewhere.
THX to Matti "Mictlantecuhtli" Lev��nen for testing, Rod��ric Vicaire
(a.k.a. Ingenu) for OpenGL wisdom, and Stefano Ceccherini (a.k.a Jack
Burton) for asking me to fix SDL on BeOS :).
