This is the wrong place to do this, but it will serve for now...

My notes are formatted like this.
* '''''Specify a limit to the precision of all positional elements.'''''
'''DONE''' trimming precision was my first priority.  precision can be set to -1 (off) or 0..9.  islint gives an extra decimal to transformation floats, so if you set prec=1, a matrix will have values to two decimal places.  This is to preserve a little sanity at a low cost should there be nested transforms.

'''Not done, easy''' I like to have an id on everything.  I usually want something more useful than path1234, but that requires either human intervention, or a targeted generator.  I can add it as an option, '''low priority'''
* '''''Clean up Definitions'''''
'''Not done, moderate, low priority''' Generally I think this section needs a bit of work.  I don't use InkScape for gradients at all, but I could.  InkScape creates a lot of gradients and creates and references linear gradients when it needs a radial gradient.  It should be possible to do a lot of cleanup here.

I've started contributing to InkScape in my own way, I have made a dent on a filter to sanitize InkScape.

My motives are purely selfish. I'm one of the authors of SVG, I work with SVG, and I find InkScape to be an excellent tool, but I spend a lot of time editing InkScape output with vi to clean it up for use in dynamic web apps (mostly). A task with very low entertainment value. Writing filters is more fun.

islint is pretty useful to me as is now, it has a way to go before it will serve as a general filter for InkScape.
