Vector stroke gradient subtle rendering bug

Recently, while importing some SVG files with gradients (created using
Inkscape), I found a bug while rendering gradients in vector graphics.
The same code produce two opposite, incomplete and incorrect results
on LiveCode 6.1.2 and LiveCode 6.5 (or later).


I used an Alpha version of the stack "SVGL plus Gradients" to import
two small SVG files, included within linked zip file. Please notice:
this Alpha version is incomplete and just must be used to test this
very specific vector gradient bug.

Text from attached stack. (Stack also includes images and vector graphics):

(CARD 1)
To the Left, a vector graphic imported into Livecode from a file named
"gradient05.svg" using LiveCode 6.1.2 on Ubuntu Linux.
To the Right, a png bitmap screenshot  of the same file
"gradient05.svg" opened in Google Chrome.
Notice: Stroke Gradient renders correctly, but Fill Gradient renders
in the wrong place.
Click the button "Go next Card" to watch how LiveCode 6.5 and later
renders the same file.
----------------

(CARD 2)
To the Left, a vector graphic imported into Livecode from a file named
"gradient05.svg" using LiveCode 6.6.2 on Ubuntu Linux.
To the Right, a png bitmap screenshot  of the same file
"gradient05.svg" opened in Google Chrome.
Notice, Fill Gradient now renders correctly, while Stroke Gradient
renders in the wrong place.
----------------

Check the attached zip file that includes two LiveCode stacks and two
small SVG files (created with InkScape).

Inside the zipped file, there are two simple SVG files  that you could
import into LiveCode 6.1.2 and LiveCode 6.5 or later (including
version 7) to compare the differences.

It's a VERY subtle rendering bug, but effectively will cause many
headaches if you are trying to import SVG files with gradients. I have
included (among the linked files) an Alpha version of the original
SVGL stack with code to import ONLY Inkscape gradients.
