Enable fallback to common defaults

[kurkle]

As reply to: #740 (comment)

I'm sure I missed some common options, but those can be added in subsequent pull requests.

I was testing the same thing, passing the common to updateElements.

This is not really optimal, feel free to create better alternative:

Filename	Size	Change
dist/chartjs-plugin-annotation.esm.js	15.5 kB	+294 B (+2%)
dist/chartjs-plugin-annotation.js	15.6 kB	+298 B (+2%)
dist/chartjs-plugin-annotation.min.js	9.84 kB	+102 B (+1%)

I don't know how but I'm gonna think about. ;)

EDIT: Maybe moving more options in common defaults, the size could be decrease, at least close the current size.

Maybe its tolerable now:

Filename	Size	Change
dist/chartjs-plugin-annotation.esm.js	15.4 kB	+246 B (+2%)
dist/chartjs-plugin-annotation.js	15.5 kB	+251 B (+2%)
dist/chartjs-plugin-annotation.min.js	9.8 kB	+67 B (+1%)

Would need to do this somehow without deepMerge to make it smaller (and faster probably too)

[stockiNail]

just thinking loud, could we use the proxies created by CHART,JS instead of the simple objects (which needs deep merge)?

I don't recall anymore why we are resolving the options to simple objects. But the proxy probably has a list of all the keys resolvable. Lets see.

I'm using your branch locally to do some tests. I can confirm you that it doesn't need to set drawTime options separately.

[stockiNail]

Having done some tests, this PR can address to centralized common options in the common but it doesn't solve the issues about duplication of code of callout (for instance).
This is because callout node is a subnode of label one (for line) instead for label is a subnode of root one, therefore fallback is not resolved anyway.

[kurkle]

There are some issues still with the fallback definitions, I'll test some more to be sure what's wrong.
