Detailed Description

Encodes a Path into Slug band decomposition format for GPU rendering.

The encoding pipeline:

1. Convert cubics to quadratics (Path::cubicToQuadratic)
2. Split curves at Y-monotone points (Path::toMonotonic)
3. Compute path bounds and determine band count
4. Assign curves to bands and sort
5. Generate a small conservative whole-path bounding polygon

The output EncodedPath contains all data needed to fill the path on the GPU.

EncodedPath donner::geode::GeodePathEncoder::encode ( const Path & path, FillRule fillRule, double tolerance = 0.1 )

static

Encode a path for GPU rendering.

Parameters

path	The path to encode. Will be preprocessed (cubic→quadratic, monotonic split).
fillRule	The fill rule (non-zero or even-odd) - stored for the fragment shader.
tolerance	Quadratic approximation tolerance (default 0.1, suitable for text-size).

Returns

Encoded path data ready for GPU upload, or empty if the path is degenerate.
