Change #254110

Comments

avfilter/vf_drawvg: support color expressions as setvar/call arguments.
The arguments for `setvar` and `call` commands can be colors (like `#rrggbb`).
This replaces the previous trick of using `0xRRGGBBAA` values to use colors as
procedure arguments.

The parser stores colors as the value expected by Cairo (a `double[4]`). This
array is allocated on the heap so the size of the union in `VGSArgument` is
not increased (i.e. it is still 8 bytes, instead of 32).
