Specifies font weight. The values 'normal' and 'bold' are supported for
most fonts. Not all fonts have a variant for each of the numeric values,
in that case the closest one is chosen.
Set to false to remove extra font padding intended to make space for certain ascenders / descenders.
With some fonts, this padding can make text look slightly misaligned when centered vertically.
For best results also set textAlignVertical to center. Default is true.
