Fix slope plane rotation and alignment (resolves #508)

Software	OpenGL

Holy shit, finally! At long last! Let's go!!

Ooooooooogh, godspeed you funky cat

changed title from WIP: Fix #508 to WIP: Fix slope plane rotation+alignment in Software (resolves #508)

unmarked as a Work In Progress

added 1 commit

• 85c53b35 - Use old routine for PO2 spans

Compare with previous version

changed title from Fix slope plane rotation+alignment in Software (resolves #508 (closed)) to Improve slope plane rotation and alignment in Software (resolves #508 (closed))

Since this merge request is no longer in WIP, I want to mention about the fact its still not matching the OpenGL flat alignment, which is supposed to be the correct one to my knowledge, probably you couldn't fix it and that's why you replaced "Fix" with "Improve".

After checking it I still see some differences between the two renderers
