14f8673644 font: add a MeasureString function, not just a method.
It can be useful to measure some text without having to set up a Drawer.

5ae59125bf shiny/font: have Face.Glyph return an advance width, not a new dot.
This is consistent with Face.GlyphBounds and Face.GlyphAdvance.

ab08d42a8a shiny/font: add Hinting, Stretch, Style and Weight option types.
These will be used by other vector font packages, such as the truetype
package, to select specific faces.

e87ffe258c shiny/font/plan9font: implement ParseFont.
Also delete font.MultiFace. We can resurrect a font.MultiFace type if we
need it in the future, but for now, it's simpler if it lives in the
plan9font package.

eecb4e626f shiny/font: new package for drawing text on an image.
Package font defines an interface for font faces.

Other packages provide font face implementations. For example, a
truetype package (not part of this CL) would provide one based on .ttf
font files.

This CL also introduces the golang.org/x/exp/shiny/font/plan9font
package, a concrete implementation of the font.Face interface for the
Plan 9 bitmap font format.
