Several little things:

Clean up of the input selected for the opengl x window in linux.
Fix a potential segfault when taking a screenshot (happens consistently when using "Save Targets" from the video debugger window).
Fix a memory corruption error that results from the wrong image size being passed when dumping textures.
Make the screenshot hotkey configurable.
