Removed commented code, fixed warnings
Created enums for cursors.
When pointer goes over a control, reset it to the hand cursor.
Fixed order of mouse transit "messages". MOUSE_INSIDE was sent
before MOUSE_ENTER.
Moved most graphics methods (StrokeRect, Mirror, etc) to Bitmap.
Remove no longer used code
Add a flag to the Bitmap constructor to be able to use a bitmap
with a SDL_surface and not free it in the destructor (for the screen surface,
for example)
Reimplement GraphicsEngine::StrokeRect() with the new Bitmap api
Forgot this one
Protect the calls to BamResource::Frame() with try..catch
