Major Changes In SketchBlock 2.1

Change from a ARGB32bit to ARGBfloat colour representation
The internal colour data for SketchBlock images etc is now stored in a high
dydnamic range format, ustilise floatng point values for each channel. This
gives major benefits in terms of speed (15% increase) and the subtlelty of
shading effects handleing HDR iages etc. at the expense of a higher memory
footprint. The old 32bit format files can be loaded in the SketchBlock 2.1 but
files saved will be in the new floating point format and so will not be
backwards compatable.

Colour Selection Window
A new more advance colour selection window which allows easy seection by HSV or
RGB values.

Transform filters
Transform filters have been interoduced which allow processing of images in
mamny ways. Initialy including , rotate, flip, gamma, rgb adjust. contrast etc.

Scale / Resize Layer Script
A new proaction based script for scaling cropping or extending layer sizes

Rotate Script
A ProAction script to manage rotaing layesr using the "Rotate"
transformfunction.
