Check out THEMES.md for more info.
If a theme.xml is not found in a system's directory, ES will now check for $HOME/.emulationstation/es_theme.xml. If present, it will load that. Fixed GuiGameList image data not updating on system change/initial startup. (finally!)
~ and . are now expanded in theme image paths. Theme percentages should now work properly. See changelog (August 10) for more.
Sped up image rendering a bit. Added a framerate display - uncomment the #define DRAWFRAMERATE line in GuiGameList.cpp to see it.
