Textured shapes get incorrectly set as PAINT_NONE fill

[mcclure]

If a shape's "fill" property is an url(), then attr->hasFill gets set to 2, but then at this point NanoSVG when checking for hasFill 2 checks to see if there's a gradient and if there's no gradient it just sets the shape fill type to NSVG_PAINT_NONE. This is causing my app to misbehave because it handles PAINT_NONE in a particular way and even if it can't currently access the fill url() through nanoSVG currently, it's important to know it is filled.

I have locally patched this with:

I could create a PR, but I don't know if this is how you want it done upstream because nanosvgrast won't know how to deal with the new NSVG_PAINT_SPECIAL type.
