Support full `SkTwoPointConicalGradient`

[wmedrano]

Would it be possible to add start radius to the two point conical gradient? I'm rasterizing NotoColorEmoji and noticed a few emojis require this feature.

From src/shaders/radial_gradient.rs

/// A radial gradient shader.
///
/// This is not `SkRadialGradient` like in Skia, but rather `SkTwoPointConicalGradient`
/// without the start radius.
#[derive(Clone, PartialEq, Debug)]
pub struct RadialGradient {

I'm currently prototyping support by looking at skia as a reference.

Only if someone would send a patch.

You could also try using vello_cpu, which supports two-point conical gradients and has built-in rendering support for COLR emojis.
