Subject: [PATCH] Fixed bug 2640 - Unable to SDL_SetRenderTarget to original
 surface for software renderer without a window

Damian Kaczmarek

Basically this bug is probably not a common use case. My goal is to allow rendering totally without a window, for example to a screenshot and I need to rely on SDL_SetRenderTarget to properly work for a purely software renderer created by SDL_CreateSoftwareRenderer.
