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.

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).

9c864f3e99 common: more accurate clipped viewport rounding 
Replaced ceil and direct casts with nearbyint to improve
viewport size calculation. This ensures consistent

44075aa0f0 sw_engine: Improved the blur performance by 12% 
Applied the compromised approach for the gaussian blur
since the effect is a bit burdensome for cpu processing
as animatable effects.

- Optimized performance and quality with negligible observable differences.
- Disabled the border option until specific use cases are identified.

sw_engine: Fix buffer overflow in texture mapping rasterizer 
Fix heap buffer overflow in texture mapping rasterizer by adding proper
bounds checking for texture coordinates. This prevents accessing memory
