In libcairo, colors are defined as 4 separate components, and each one is double between 0 and 1. Before this commit, colors stored in variables (like `defhsla`) were converted to a `0xRRGGBBAA` value, which introduced some issues due to rounding errors. Now, when a color is assigned to a variable, the original values (a `double[4]`) are stored in a dedicated array (`color_vars`), so no conversion is needed. This change also reduces the cost of reading a color from a variable (no need for `av_be2ne32`, or the `color[i] / 255` operations). Signed-off-by: Ayose <ayosec@gmail.com>
