d5125bd839 common: add missing condition while trimming 
The idea of introducing epsilon during trimming was to
eliminate the occurrence of short segments whose length
would be zero when higher computational accuracy was used.
By mistake, during the refactor of 8ed4c2f302,
one of the conditions was lost. Fixed.

3a0e1eadae gl_engine: apply common trimming logic 
The trim-related implementation has been removed
and replaced with the one available in common.
The trimPath get() fun changed to be internal.

8ed4c2f302 sw_engine: move trimming logic to TrimPath 
The trim handling from sw_engine has been removed.
Instead the common logic from the TrimPath structure
is used.
On the sw_engine side, the dashed outline is now
used for both: dashed and/or trimmed strokes.

78cfc33f4c lottie: support frame tweening feature 
frame tweening allows user to interpolate two frames
over a speicified duration. This Tweening functionality
can be particularly powerful when combined with state-based
(a.k.a. Marker) animation playback in Lottie.

For example, apps support state machine based animations,
where the transition sequences between states are not linear
and can occur in highly irregular directions.

Experimental APIs:
- Result LottieAnimation::tween(float from, float to, float progress)
- Tvg_Result tvg_lottie_animation_tween(Tvg_Animation* animation, float from, float to, float progress)

41f10b9702 sw_engine: fix color burn/dodge edge cases 
Dodge d / (1 - s):
- handle d = 0 first to avoid 0/0 when s = 1
- for d != 0 and s = 1, the formula results in d/0 (infinity),
  which maps to 1 in the 0-1 range (or 255 in the 0-255 range)

Burn 1 - (1 - d) / s:
- handle d = 1 first to avoid 0/0 when s = 0
- for d != 1 and s = 0, the formula results in  1 - 0/0 -> 1 - inf = -inf
  Negative infinity in the 0-1 range corresponds to the minimum possible
  value, which is 0 (255 if we operate in 0-255 range).
