Description Øyvind Kolås (pippin) 2006-09-27 16:59:26 UTC 
Please describe the problem:
The affine operations do their computations on 8bit data, this makes GEGL
convert back and forth from 8bit to 32bit floating point when doing
doing it's computations currently add to this that it is an expensive coversion
for babl (even if optimized), it should be avoided, both for this reason and
because it makes any operation involving transformations not be HDR compliant.

Steps to reproduce:

Does this happen every time?

        * operations/transform/linear.c
        * operations/transform/nearest.c: Updated to use float instead of u8.

        * docs/gallery/clones.xml: Reduced blur radius by 1/3 due to recent
        changes in the gaussian-blur.
