LibGfx: Make text painting better at aligning vector fonts vertically
This is achieved by simplifying the logic in TextLayout. We get rid of all the various ways that the layout bounding rect can get cropped. Then we make sure to use the right pixel metrics. Finally we use the font's own line gap metrics instead of hard-coding 4. The end result is that text painted with vector fonts now gets pretty reasonable vertical alignment in most cases.
