Clip paths not working with transforms

[ModisR]

I had expected SVG to apply transforms first and then clips. Turns out this isn't the case and I'm now left scratching my head on how to solve this.

Current thoughts are to forget SVG transforms and encapsulate the necessary arithmetic ourselves.

to have an opinion on that i have to educate myself on clip paths first. but at least i consider my modules doing all the arithmetic from the beginning, if i am not wrong, so these hopefully do not contribute to this issue.

couldn't wrap my head around the dependencies of groups and clipPath ids.
added a method clipPath in addition to clipShape, which returns the id of the generated clipPath that can be assigned to the to-be-clipped shape. this seems to work and having no issues (at least) with the default transforms. see gc gallifreyan and the respective method.
