SVG textPath transforms the shader space for each glyph

Project Member Reported by fmalita@chromium.org, Mar 14 2018 
*I think* textPath glyph positioning is supposed to be a purely layout/geometric operation, and not interfere with the gradient/pattern space.

But in our implementation it seems to contort the shader space for each glyph (presumably due to mucking with the global transform).

Compare attached results vs. FF (expected behavior?).

Yes, the paint server should apply in the coordinate space of the element and not that of each individual glyph (digging that out of the spec may prove a challenge though...) And while it wouldn't be an impossibility to fix in the current shape of things, it will take some wrangling. Being able to "lock" the transform on the shader would've made things easier =).
