harmonize color regex & ignore SVG default black

[xerc]

found the last one ;)

@metafloor do you remember/know if fill-rule="evenodd" is only used for maxicodes inner rings ?

[metafloor]

All of the drawing in BWIPP uses the postscript default nonzero winding rule. But the filled regions never intersect, so it doesn't have any effect.

What are you trying to achieve with testing for white background and path filling? Is it a bug you have found or something else?

[xerc]

after sleeping this would be the best solution to ignore SVG default fill color if it is "black"
could even change the "header" to <svg [..] fill-rule="evenodd" stroke="currentColor" fill="currentColor"> for more flexibility afterwards

I don't see the need for this and it breaks backward compatibility. Since you won't explain why you want this change, I will assume it's to allow css rules to specify the fill.

If that's the case, just use a regexp to get rid of the fills. Something like:

svg = svg.replace(/ fill="#[0-9A-Fa-f]{6}"/g, '')

A similar approach can be used with stroke color as well.

not shure what to explain ; SVG default color is/was always black

bwt/ the info about currentColor was just a question if you "like" =-> already using replace 4 cleanup
