description:
Scaling dimensions of underline by font height.
Currently,
- offset of underline is fixed to 1-row from bottom of characters, and
- height of underline is fixed to 1.
Both are good for standard 8x16 fonts. However, it is too thin for
larger fonts, especially when used on display of high resolution.
Also, 1-row offset of underline is ugly for small fonts, e.g.,
spleen5x8.
Therefore, adjust offset and height as,
- no changes for standard 16-height fonts.
- scaling by font height for larger fonts.
- set offset to zero for fonts of height smaller than 16.
