diff engine/core/video/renderbackend.h @ 634:5f381fa34769
* Added the clearBackBuffer() function to the renderbackends.
* Renamed setClearScreen() to setClearBackBuffer()
* The SDL render backend now honors what was set with setClearBackBuffer()
* Documented testRenderedViewPort()
* The OpenGL backend no longer clears the screen every frame by default. testRenderedViewPort() takes care of clearing the screen for now. Note: if the user overrides the default and enables clearing of the backbuffer that it may be cleared twice in one frame (OpenGL only)!
