GUI Help and Tips

Problem: when using GuiBitmapButtonCtrl.setBitmap(), the application is very slow (e.g animations are not played fluently)
Solution: It seems that changing the texture of a BUTTON uses up too many resources. In this case use a normal GuiBitmapCtrl and a GuiMouseEventCtrl for button functionality instead.
Problem: When changing the game resolution the rows of GuiFrameSetCtrl are changing as well.
Solution: In GuiFrameSetCtrl the field autoBalacing must be set to true!!
