this should now be correct and much simpler to maintain from now on.
downside is that it breaks the appearance of quads with tex repeat on,
but i don't think anyone ever used this ever since i've added the Lua functions;
so i'm just calling it broken in older versions and move on.
- Use indexed triangle rendering, no more GL_QUADS for tiles
- Fix aquarian text on maps
- Tile tex repeat mode works again
Known broken:
- Editor
- Tile repeat with grid effects
class Element is completely gone.
(The files are still there but no longer compiled in. Will delete later)
Broken still:
- support for vertical flip
- the editor
- culling
