- When switching to fullscreen OpenGL mode, only use some predefined, common
resolutions. Fixes the problem in Linux of getting weird refresh rates, and will hopefully fix the fullscreen OpenGL Windows problems as well. - Removed the option of automatically pausing when toggling fullscreen/ windowed mode since it was getting on my nerves :) git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@233 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
