Maybe a duplicate of #11018. A shading pattern is used as the "color" when a path is stroked. |

Previously, we set the base transformation and pattern matrix directly to the main rendering ctx of the page, however doing this caused the current transform to be lost. This would cause issues with things like shear missing so the pattern was misaligned or when stroke was used the scale of the line width or dash would be wrong. Instead we should leave the current transform and use setTransfrom on the pattern so it is applied correctly. For axial and radial shadings I had to create a temporary canvas to draw the shading so I could in turn use setTransform. Fixes: mozilla#13325, mozilla#6769, mozilla#7847, mozilla#11018, mozilla#11597 The following already in the corpus are improved: issue8078-page1 issue1877-page1

Configuration:
Steps to reproduce the problem:
What is the expected behavior? (add screenshot)
In Acrobat the border is thin and the gradient fades from the center to left and right
In Firefox built in pdfjs the border is a little bit thicker and the gradient fades left to right
In our own app using 2.2.228 the border render the same as with FireFox builtin.
In our own app using 2.3.200 the border is very thick and fades left to right
What went wrong? (add screenshot)
PDF rendered differently between 2.3.200 and 2.2.228, border is double thickness
