Currently we have:

the following kernels:

  • Dirac (added in this PR)
  • Box
  • Triangle
  • Gaussian
  • Mitchell
  • Kaiser

Kernel modifiers allow you to create a new kernel as a modifications of the above kernels.
Currently we have the following 4 kernel modifiers:

  • Scaling & Stretching of a given kernel (removed in this PR)
  • Different kernels per channel
  • Derivative of a given kernel
  • Convolution of two kernels

After removing CScaledImageFilterKernel, we will be eliminating the first one.

To eliminate the Scaling & Stretching modifier, means to make scaling and stretching an inherent property of the filter kernels.

TODO

  • Implement numerical integration for "double" convolution.
  • Implement specializations for certain reconstruction and resampling kernel combinations.
  • Fixes for Asset ImageFilters do use extents in texel dimensions incorrectly #436.
  • Make filters work with BC formats.
    • Fix BC1 and BC3 decoding.
  • Add a concept for blittable kernels.
  • Remove CScaledImageFilterKernel.
  • Make kernel supports run-time changeable (affecting Mitchell and Kaiser).
  • Cherry-pick some fixes from the ditt branch. Check this private Discord link.
  • Add derivative and smoothness in kernel weights.

…unt validation check to CBlitImageFilter, update all onDecode implementations - remove encode buffer, do swizzle on input decode buffer in-place and respect channel count, update all onDecode references, make sure all compiles
