Improve FastGaussianBlur performance #86

Closed ahausladen closed 2 months ago

ahausladen commented 2 months ago

This pull request improves the performance of FastGaussianBlur by skipping identical color weight calculations in BoxBlurH and BoxBlurV. It also reduces the DivOneByXTable memory usage from 512KB to 8KB.
