Description tomaszewski.p 2013-03-10 15:55:13 UTC 
Created attachment 1067 [details]
Modifies drawing and blitting functions to include viewport settings.

According to API description:
SDL_RenderSetViewport - Use this function to set the drawing area for rendering on the current target.

DirectFB renderer in DirectFB_UpdateViewport function just sets clip on surface, instead of moving drawing area.

Attached patch uses set clip rectangle to move {x,y} coordinates during draw and blit operations to be compatible with API description.
