There has been a tiny change to Varvara(#uxn) where the #00 Screen/sprite value will, from now on, only clear the pixels that are present in the sprite data at Screen/addr*. I've ported all the 100r roms to support the change, and updated the docs.

updated documentation: wiki.xxiivv.com/site/varvara.h
mailing list: lists.sr.ht/~rabbits/uxn/%3CCA
discussion: lists.sr.ht/~rabbits/uxn/%3C69
example file: git.sr.ht/~rabbits/uxn/tree/ma

The blending modes in Varvara, with the example source code in Left behind.

@neauoire What hardware and OS do you host Varvara on now?

@mirth It depends, but for the summer I'm only working from the pinebook, it has manjaro on it.

@neauoire Thanks. It's interesting to think about how much surplus capacity there is on modern hardware for so many tasks.

@mirth yeah, it's nice to explore this. I read in an article recently the phrasing "articulating the value absence" which is really nice.

@neauoire I believe the launcher uses /projects/library/load-rom.tal which uses an old screen clearing routine (instead of pixel fill) which fails to properly clear the screen after this change.

@tbsp Yep! I've noticed that. I have a new version in the works that uses the same launcher as in potato, and clears the screen properly.
