RFE: polygonal grid

Here's a picture of what I'm looking for (8 sections, equal x/y spacing, and an arbitrary extent limit).

I actually decided to start working on this myself (this is a screen shot of inkscape :-D)... the rendering logic is a bit crude at the moment (not clipped, and see aforementioned 'arbitrary extent') and I haven't even started work on snapping, but as shown, it's at least far enough to get the idea across.

Rudimentary clipping, as well as calculating the needed extents to fill the viewport, is now done. Code is at lp:~mw-triad/inkscape/polygonal-grid. (Snapping isn't started yet, but next on the to-do list, as rendering is now at an acceptable point.) Right now my thought is to file a separate request for grid extents, since it makes more sense to have this otherwise done, then tackle general extents in one go.

There are a couple issues for which I don't see obvious solutions; if some knowledgeable person could help out, that would be much appreciated...

- Grid units is initially unset.
- Sometimes a line or part of a line does not render.

Also, the lines are not clipped to the viewport. This doesn't seem to matter from a correctness standpoint; not sure if it is worth changing for performance?

Okay, I have this in a state where it is working sufficiently for my needs. Patch series (git-am format) attached, or see branch at lp:~mw-triad/inkscape/polygonal-grid.

Besides the previously mentioned minor points, the configure page icon is also missing, but it is not clear to me how to go about adding one?

Hi, Matthew did you get to implement the polar grid too?

In the case of a polar grid, options to set the number of sectors and the rings width would be useful too.

@Antonio, no, and given that the inkscape devs don't appear to care about contributions, I doubt it's ever going to happen. Anyway my main use case is/was something for which I'm hoping to eventually be able to use a different program altogether.

FWIW, obviously the configuration options for a polar grid would be center, r and θ step sizes, and possibly also something to tweak how θ lines are suppressed near the origin.

We actually do care about contributions. I'm sorry to see that we missed this patch from so long ago. We do welcome contributions I'm sorry that you feel otherwise. I did try to apply your patch to my local copy, but as you can imagine with the amount of time that has passed, it has bitrotted. If you would be willing to re-submit it, I'd be willing to test and give it a look over,

@mw-triad how about respinning your patch?
