Summary: (Win)OpenGL loses bitmap data on fullscreen mode changes

Initial Comment:
Modifying ex_fs_resize to use an OpenGL display, the following error can be observed:

The image of mysha the mouse is not being displayed after pressing '+' to change the fullscreen resolution.
The bitmap memory seems to be all zeroes after the first conversion to a memory bitmap 
inside 'destroy_display_internals' in 'wgl_disp.c'.
