RGB/XY graphics code helpers
A package for graphics coders, to duplicate a line or region, handling rgb(a), xyz(w), [0]-[2] etc. To use, place point on a line to be duplicated & transformed. That line should have a pattern like the following: * .x (will be transformed to .y .z .w) * ->x (similar) * .r (will be transformed to .g .b .a) * ->r (similar) * red (to green blue alpha) * [0] (to [1] [2] [3]) Use C-u (repeat count) to set total number of repeats. Defaults to 3 if the line/region contains rgb-type text, otherwise 2.
