VBoxSDL.cpp@ 81624

Last change on this file since 81624 was 81537, checked in by vboxsync, 5 years ago

FE/VBoxSDL: Added first support for SDL2 (by setting VBOX_WITH_SDL2). Very rough / hacky by now and needs more testing first before enabling by default. Also fixed non-starting with SDL 1.2.x on Windows hosts.

Known limitations / todos when running with SDL 2 for now:

No alpha channel support for cursors.
No mouse wheel support.
Desktop geometry handling needs a revamp for multi monitor setups.
Check / revamp dirty rectangle blitting.
OpenGL renderer needs testing wrt texture blitting.

Property svn:eol-style set to native
