/* Applies spacing adjustments to clusters.
|
|
|
|
Adjustments are applied in the following order:
|
|
|
|
1. Negative adjustments
|
|
|
|
Leading and trailing spacing could be negative, at this step
|
|
only negative ones are actually applied. Leading spacing is only
|
|
applied to leading glyph, trailing - to trailing glyph.
|
|
|
|
2. Minimum advance width
|
|
|
|
Advances could only be reduced at this point or unchanged. In any
|
|
case it's checked if cluster advance width is less than minimum width.
|
|
If it's the case advance width is incremented up to minimum value.
|
|
|
|
Important part is the direction in which this increment is applied;
|
|
it depends on direction from which total cluster advance was trimmed
|
|
at step 1. So it could be incremented from leading, trailing, or both
|
|
sides. When applied to both sides, each side gets half of difference
|
|
that brings advance to minimum width.
|
|
|
|
3. Positive adjustments
|
|
|
|
After minimum width rule was applied, positive spacing is applied in the same
|
|
way as negative one on step 1.
|
|
|
|
Glyph offset for leading glyph is adjusted too in a way that glyph origin
|
|
keeps its position in coordinate system where initial advance width is counted
|
|
from 0.
|
|
|
|
Glyph properties
|
|
|
|
It's known that isZeroWidthSpace property keeps initial advance from changing.
