This message may be repeated (sorry) - my messages never seem to reach the

The following function is just a little something i whipped up to make
gradient images on the fly rather than save a lot of pre-generated images.
Any comments on making it more flexible etc would be appreciated ;-)

Comment: {
this release allows you to perform standard X / Y gradient fills
similar to the gradient tools in photoshop / gimp / paintshop pro
'n' degree free gradients will have to wait for a new view release
due to constraints on rotate
