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
approach with the fastTrack case in sw_engine.

- 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
outside of the allocated image buffer during texture sampling and
interpolation.
