Gotta say, this opens up a whole lot of new, awesome possibilities
But this negative stretch thing really bugs me. Also, it doesn't only affect ganis like I'd first thought. Negative stretch effects don't seem to work at all for me using v6. Running an XFX Radeon HD 5850 with the 11.2 drivers. I'll give it a try with the new 11.3 drivers soon-ish, but I'm too lazy to install them right now, sorry
Edit: For whatever reason, it now works (after deleting my Graal v6 folder and just firing up a fresh Graal.exe). It does show the flipped sprite, so that's cool. However, is it possible that there are some kind of quirks done to the rotation math after flipping a sprite? It seems my flipped and rotated sprites are 180 degrees off, while the non-flipped rotated sprites are still fine.
