Aligning text (left/right) requires access to more glyph metrics then AdvanceX. The side bearings (LSB/RSB) are required to know how much "whitespace" there is left/right of a glyph.

I'd like to propose a GlyphMetrics method which calculates and returns the LSB, RSB, Width and AdvanceX.

CL with working prototype is on its way.
