Notes cont.

Icon theme

Organize in several subdirs (similar to icon theme contexts, or based on icon sizes) instead of maintaining one flat directory mixed with other graphic resource files?
...

Icons

Copy metadata (license info) from the original icons.svg file?
Add viewBox (with integer sizes if feasible)?
...

Guidelines for editing and new icons

Known restrictions due to librsvg as rasterizer?
Flat structure (no deeply nested groups, transforms) preferred?
...

@Tavmjong - I can offer to help with fixing partially broken icons, and cleaning up the others, though I'd rather wait until any possible bulk changes to the icons are done, and the directory structure has been decided on (which would likely be required to support switching to alternative themes).
