Say I want to draw a color gradiant (shade of colors) from RGB

since this can be the case: I ask the user the start and end colors
and (s)he can place &c000000 or click on a Canvas rect to choose a
color in the OS palettes]
As recently discussed on the Blurry Canvas thread.
Download the ScriptPictureEffects from
http://www.oofile.com.au/downloads.html#DownloadREALbasic
You can use the method in the PictureEffectsScripter class, test it
in that app with a script like this:
LinearGradient &cFF2020, &c000000, 0
Note that it allows for a rotated gradient, using PictureEffects to
rotate the picture. At an angle of 0, it just draws straight onto a
Graphics object.
