Re: [AD] fixes for some al_resize_display cases in Windows

[Dennis-Busch@xxxxxxxxxx]

New patch is attached (also fixes OpenGL bitmap preservation between 
fullscreen mode changes now:
https://sourceforge.net/tracker/?func=detail&aid=3543463&group_id=5665&atid=105665 ).

Patch notes:
* fixed missing/incorrect resize events under Windows   in
 Direct3D and OpenGL displays (could be seen in
 ex_display_events)

* fixed a case where changing fullscreen mode in D3D via al_resize_display
  caused a crash and loss of loaded bitmaps information causing
  the bitmap not to be converted and thus disappearing after mode change
  (problem could be observed running ex_fs_resize)

* fixed a case where changing fullscreen mode in OpenGL(Windows) via
  al_resize_display cause nothing at all to be rendered after the mode change

* fixed OpenGL(Windows) bitmap preservation between fullscreen mode changes
  (problem could be observed running ex_fs_resize with an OpenGL display)
  (major credits to Elias who helped debugging this through screenshots
   of debugger states and by providing tons of knowledge)
