Fix jitter of polygon/polyline after reverting from 2-step positioning

[ignatz]

Previously, the canvas was positioned in two steps using a Positioned widget, which was removed due to its own precision issues. Now the canvas needs to be redrawn whenever the viewport changes, not just rotations and zooming but also panning.

Hey @ignatz.
Please also note #1513: we think the batching changes may have caused some issues when rendering polylines with borders - not sure how we didn't catch this before!
Fixes for the broken status checks (support for Flutter 3.10) available in #1512.

Why the "saveLayers" issue wasn't caught is probably easy to answer: there are no tests, no examples, and the docstring seems to discourage its use.

As to this fix, this is unrelated.

Unrelated to this fix but FYI, I was able to convert my App to Flutter 3.10 w/o many issues. I guess that's due to the use of my own custom tile provider 🤷

Yeah, everything is working, but the checks aren't - there have been some deprecations and stuff.

(Please pull from master. Only Flutter 3.10 is now supported.)

LGTM. Thanks :)
