2023-06-13*: smattering of random small fixes to silence -WallVito Caputo
I thought the build was already using -Wall but that seems to not be the case, maybe got lost somewhere along the line or messed up in configure.ac After forcing a build with -Wall -Werror, these showed up. Fixed up in the obvious way, nothing too scary.
2022-05-23*: silence some more clang parens warningsVito Caputo
2022-05-01til_fb: add draw flags for controlling texturabilityVito Caputo
Just adds TIL_FB_DRAW_FLAG_TEXTURABLE so callers can granularly inhibit texturing if desired.
2021-10-01*: librototiller->libtilVito Caputo
Largely mechanical rename of librototiller -> libtil, but introducing a til_ prefix to all librototiller (now libtil) functions and types where a rototiller prefix was absent. This is just a step towards a more libized librototiller, and til is just a nicer to type/read prefix than rototiller_.
2019-11-16libs/txt: add minimal ascii text rendererVito Caputo
This is as basic as it gets, the only fanciness is it recognizes newlines and supports horizontal and vertical justification. As this is intended to be run from potentially threaded fragmenter renderers, it receives a fragment and *frame* coordinates for the text to be rendered. If the text doesn't land in the given fragment, nothing gets drawn. Currently this is not optimized at all. There's a stubbed out rect overlap test function which could be used to avoid entering the text rendering loop for fragments with zero overlap, that's an obvious low-hanging fruit optimization. After that, skipping characters that don't overlap would be another obvious thing. As-is the text render loop is always entered and the bounds-checked put pixel helper is used. So every fragment will incur the cost of rendering the full string, even when it's not visible. For the rtv captions this isn't a particularly huge deal, but stuff to improve upon in the future.
