21a21a63ab common: fix trimming 
By mistake > was used instead of >=.
The issue was observed for trim when
the trim length was exactly zero.

7c87d8e632 common: move&fix trimming wrapping logic 
The logic of interpretation of trimming start and
end values has been moved to the sw_engine,
so the values provided by the user are not modified.
No logical changes in the interpretation alg.

For pairs of trim's start/end values where the distance
between begin and end is >= 1, the entire stroke should
be drawn, but instead, nothing or only part is drawn. Fixed.

Stroke trim docs fixed.

ttf_loader: Basic support for composite glyphs loading (#2600) 
Adds the ability to load some composite glyphs and prevents an error when a composite glyph is used.

Implementation based on ttf glyf table documentation: https://learn.microsoft.com/en-us/typography/opentype/spec/glyf

There are still some missing features like scaling, parent glyph point based positioning etc. I think this is a topic for future work. Howerever, it looks like implemented features are enough for utf-8 latin subset in major fonts.

issue: #2599

828f8e0767 sw_engine: fix linear grad issue 
The restriction of the 'length' of a linear gradient
to values greater than FLT_EPSILON was causing rendering
issues in cases where it was a valid gradient with well
defined dx and dy values.
