Overview

A rasterised, cached glyph. A monochrome glyph carries alpha (a row-major 0..255 coverage array, stride padded to a multiple of 4), or nil for a glyph with no outline (e.g. space). A colour glyph (from a colour delegate, see GlyphCache) instead carries rgba, a row-major array of packed 0xRRGGBBAA pixels; for those alpha is nil. Placement fields are shared.
