related tdf#126533 vml import: fix gradient color swapping
tdf#65295 already fixed one case
by removing the test for degrees > 180
for the linear-equivalent gradients.
Unfortunately the comment wasn't also removed,
so that was confusing: removed comment.
The test for degrees > 180 is not needed
for the axial-equivalent case either: removed.
The reason for that degrees > 180 case is likely due to
negative degrees, which is a documented reason
for swapping the colors: added swap if negative degrees.
All the affected, existing unit tests are improved now:
-tdf81345.docx: famous MS example: improved header gradient
-fdo78300.docx: fontworks: hard to tell without MCGR...
