svgdom baseVal not supported

I'm using path-data-polyfill, which uses baseVal to get x/y/width/height/etc. values from <rect>, <ellipse>, etc. elements. It would be great to implement this in svgdom!

Unfortunately that's not as easy as it sounds. You basically need to intercept all access to the node to return the correct attribute. Feel free to open a PR to implement this feature!

It looks like HTMLLinkElement exposes some direct properties, could baseVal be handled in a similar manner?

The properties for which baseVal works are quite limited and well-defined per element type, at least for shapes:

rect - x, y, width, height, rx, ry
circle - cx, cy, r
ellipse - cx, cy, rx, ry
path - none
line - x1, y1, x2, y2
polyline - none
polygon - none

baseVal is useful for parsing SVG lengths, as in <rect width="10cm" height="10cm"/>. getAttribute works fine for the raw value but it would be great if svgdom could handle the lengths.

There is more. Everything in svg is animatable. Everything which is animatable has baseVal and animVal properties. For e.g. polygon you have points with a pointlist which of it also has x and y. I think its not as easy as you think it is. But if you want enhance a special bit of svgdom you are welcome to do so. If you only need some properties, just add them :)
