Public Attributes
float	pathFromPixel [4] = {}
	Inverse linear transform, two columns, pixel to path.
float	pixelOrigin [2] = {}
	Integer pixel the mapping is taken relative to.
float	pathOffset [2] = {}
	Path position of the translation's fractional remainder.

Detailed Description

Pixel-to-path mapping a Slug fragment applies to its own pixel center p: pathFromPixel * (p - pixelOrigin) + pathOffset, with pathFromPixel holding the inverse linear transform's two columns.

The fill, gradient and mask shaders all take it in this form.
