dropShadow updates

[sqwarellc]

Updates dropShadow to support flood-color and flood-opacity attributes, per side discussion in Issue #63.

The thing I'm not sure about is on Line 53 of
svg.filter.js.d.ts - should color: be SVGAnimatedString ? Or something different.

The change looks solid. I am actually lot sure what type the color has.

We only included the feDropShadow interface in the types because it wasn't in the official typescript Dom types when we released. However it was added in the meantime so we probably can get rid of the whole interface (even tho the official interface does not include the flood and opacity attributes yet. But since you rarely actually access the Dom element through svg.js, it doesn't matter too much in my opinion).

However if you want you can figure out the type yourself by creating a drop shadow filter with a flood color and print out in the console the value of the attribute:

const mydropshadow = filter.dropShadow(...)
console.log(mydropshadow.node.floodColor)

In Theorie that should print the object to the console together with its type.

Personally I would just remove the whole interface

OK, this is major beginner stupid-question time... I would like to do the test you described above to look at the floodColor attribute.

When I download my branch of the code tree to my local machine, I replace the code that loads the production version of svg.filter.js with my branch, but the resulting page just hangs with no output (and no errors on the console). What am I missing?

// original load of production version
<script src="svg.filter.js/svg.filter.js"></script>

// modified to load local copy of my modified branch
<script src="svg.filter.js-patch-1/src/svg.filter.js"></script>
