Removed shared context ability from Pbuffer (win32)

Simplify Mouse cursor positions and replace display_hwnd global variable with getCurrentHWND() (Win32)

Avoid ARB_pixel_format in Display whereever possible. Must try the path once though, to increase the chance of getting a pbuffer compatible context. If it fails, the normal path context is kept, in hope that it will support pbuffers. If not, only unique context pbuffers will be available.

Win32 part of fast Pbuffer
