- r_roundImagesDown 2 - nonpowerof2 (NPOT) support. No extension checking added yet; use at your own risk! (intended for buffer effects)

- r_parseStageSimple - working towards pcx2 support by loading shader stages with the texture last, to approximate blending functions by processing them into having alpha channels (or not, for opaque surfaces). Because I can.
- leifx filter change - indicate number of passes to the shader, so the pixel blurring order can be tweaked to further perfection (ridding the left pixel check as that happens)
