Summary: Shaped windows creation and destruction
Product: SDL Reporter: Juha Niemimäki <juha.niemimaki>

Description Juha Niemimäki 2016-03-15 18:22:10 UTC 
There might be a couple of issues with shaped windows:

1) SDL doesn't check the function pointers (like CreateShaper) before using ( https://hg.libsdl.org/SDL/file/9cec5fe32bca/src/video/SDL_shape.c#l38 )

2) Cleanup: shouldn't shaper and data be cleaned during window destruction? Perhaps SDL_DestroyWindow could check for shaper existance, and when found, call a shaper destructor function?
