Colour Manipulation

[hh]

Hi all.

Today I implemented this as part of LCImageToolBox89: Basics.

Get it _from LC 8/9_ via "Sample Stacks" of the LC-Toolbar or
http://livecodeshare.runrev.com/stack/826/LC-ImageToolBox89%3A-Basics

Uses Canvas2D (no webGL because of issues with some graphic cards)
in a hidden browser widget. Your method gives nice Effects and works
with a decent graphic card pretty fast. Needs here with LC 8/9 on a
Mac mini 2.5 GHz/IntelHD4000 for a 1920x1080 image < 500 millisecs.
