Initial styleswitcher theme looks off

Note the discontinuous line and rectangle rendering. This does curiously not happen with the other themes.

Yeah, that happens because of the tile stretch hint enabled by default in frames. This is fixed by setting the hint to false when using this tileset.

A more elaborate solution would be analysing the pixels in the filling tiles and detect automatically if they can be stretched. I'll do that later. Thanks for your report!
