Minor
Preparation for effect-independent computation of the nermal vectors.
Some fixes for issues discovered by the Multiblur app.
Beginnings of the 'Multiblur' app.
BLUR: implemented caching of the BLUR kernels.
Minor progress with Gaussian. Still need to cache the Weights and Offests tables.
Separable Gaussian Blur with linear sampling done.
Linear sampling implemented - i.e. blurring by a (2N+1)x(2N+1) gaussian kernel (centeral pixel + N pixels in each direction) requires exactly 2N + (N%2==1 ? 4:2) texture fetches.
Precompute the standard normal distribution.
minor.
Separable Box blur fully works now!
