- no longer uses GL matrix stack manipulation, all matrix math is done locally
- use fixed rotation matrixes for fh/fv
- don't touch GL buffers (fixes crash with prev. commit)
- 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
Turns out there was another renderer bug that would effectively
ignore the vertical flip if a Quad had an active ElementEffect that
used a grid (effects on numpad keys 1,2,3,5,6).
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
