Martin Fouilleul e9ecd9d521 [mtl canvas] Fix artifacts on tiger that was due to epsilon comparison for cubics equation in draw kernel. Removed that (now do <= 0), but then we need to weed out false negatives for solid triangles. So we compute if the triangle is solid in the triangle kernel and store it in the mg_triangle_data struct for now. 2023-03-22 15:02:04 +01:00
Martin Fouilleul 0d8bc824a2 [mtl canvas] bucket triangles into per-shape tile queues, then gather into tile arrays. This somewhat improves perf for perf_text test and avoids an awful degradation due to sorting in tiger test (tiger now runs at ~20fps, which is still much slower than it could be, but the triangle coverage method we're using just incurs too much cross product computations...) 2023-03-21 10:22:37 +01:00
Martin Fouilleul a4ef58f2d8 [mtl canvas] Tiling per rectangles into per-shape tile queues (linked lists of triangle indices) to avoid sorting 2023-03-20 16:46:12 +01:00

Martin Fouilleul 13f025ab21 [mtl canvas] convert triangle rasterization to fixed point 2023-03-13 15:18:18 +01:00
Martin Fouilleul 7c58145524 [mtl surface] Allow setting swap interval to 0. Note however that vsync needs to be turned off at the OS level for that to work smoothly. Otherwise, we get jittery frame rate with stalls when we run off of drawables (I suppose? should investigate some more). 
This can be done with Quart Debugger in Additional Tools for XCode.

Martin Fouilleul 5455c2a52b [ui] Allow styling overlay boxes (e.g. menu and drop-down list panels) locally. 
- Added an UI_FLAG_OVERLAY flag. When we make a box with that flag set, it is added the an overlayList in the ui context.
- After styling and static size pass, we reparent boxes in the overlayList to an overlay node just below the root node.
- Layout and drawing works uniformly on the whole tree. Overlay boxes get drawn last and steal mouse hover from boxes underneath them.

Martin Fouilleul 3682605f97 [util, formatting] changed list api to snakecase for consistency with the rest of the codebase 2023-03-08 12:00:10 +01:00
Martin Fouilleul bfc19665ce [util] 
- shorten str8_lit macro to STR8
- use strlen() in STR8 and remove str8_from_cstring(). Usage with string literal seem to always be optimized by compile-time constant, so there's little need for a confusing macro that only works with literals and breaks with pointers.
- replaced str8_unbox() with str8_lp/str8_ip

- Renamed full pattern matching API to ui_style_match_next_before/after
- Helper to style next box only (ui_style_next())

Martin Fouilleul 3615775168 [canvas] decompose image atlas API into simple rect atlas API + image atlas helpers. This avoids creating a bunch of new types/handles, and exposes the underlying image/sourceRegion so that user code can freely use these for more complex scenarios (eg drawing only a sub-region of an atlased image, or using an atlas image for arbitrary path filling) 2023-02-28 16:54:39 +01:00
