Fix for crash on large image blur sigma values.
This was crashing on the GPU path, due to a failed texture allocation.
The belt-and-suspenders fix is to:
1) Limit the GPU path to only allocate up to maxTextureSize.
2) Limit both the raster and GPU paths to reasonable blur sizes (box blur
kernel size of 1000, resulting in a sigma limit of 532).
