Multiply by a glyph-to-default rounded factor when resizing fonts

When matching to a default monospace width, big fonts like those containing symbols and emojis got too small from font resizing. Adding a glyph-to-default rounded factor to the calculation should fix that issue without losing monospatiality. Fixes pop-os/cosmic-term#69. Signed-off-by: Mohammad AlSaleh <[email protected]>
