Chad Brokaw	58c7df469d	Address review feedback ... * replace one_minus_focal_x and abs_one_minus_focal_x variables with the actual expressions * replace division by r^2-1 with multiplication by reciprocal * revert chain selects to branchy code for clarity. Branching is dynamically uniform so shouldn't affect performance * add suggested comment describing gradient kind/flags constants	2023-05-15 14:45:38 -04:00
Chad Brokaw	b103a55301	rework radial gradients ... Adds full support for COLRv1 radial gradients based on the two-point conical gradient algorithm at https://skia.org/docs/dev/design/conical/ Also adds robustness to degenerate cases in gradient encoding: * Radial where p0 == p1 && r0 == r1 renders transparent solid * Empty stops render as transparent solid * Single stop renders as solid	2023-05-09 18:09:53 -04:00
Chad Brokaw	ced6309a3b	support two point radial with r0 > 0.0	2023-05-06 03:27:53 -04:00
Chad Brokaw	a8585781cd	move atlas rect to info ... Atlas offset and image size were originally stored in the ptcl but are not tile dependent. Moving these to info saves 8 bytes per image tile.	2023-03-10 01:42:50 -05:00

Chad Brokaw	3c15bff867	Proper inverse of translation components	2023-02-22 23:08:38 -05:00
Daniel McNab	ff59839737	Move the vello crate to the workspace root (#231) ... * Move the vello crate to the root of the crate * Add warning that README is work in progress * Add newline in warning * Move the unlicense into the shader folder * Fixup wgsl-analyzer include paths	2023-01-05 09:32:09 +00:00
