Implement point() for webgl mode

[kjhollen]

Nature of issue?

• Found a bug
• Existing feature enhancement
• New feature request

Most appropriate sub-area of p5.js?

• Color
• Core
• Data
• Events
• Image
• IO
• Math
• Typography
• Utilities
• WebGL
• Other (specify if possible)

Feature enhancement details:

point() only works in 2D mode currently, but it would be great for WEBGL mode, too.

this is a somewhat self-contained issue and would be great for a new contributor who wants to write some webgl code, but maybe a little more work than some of the other issues I've labeled with level:beginner. see: WebGL Module Architecture for relevant documentation.

Hi, I'd really like to volunteer do this one.
I actually attempted this a little while ago (when working through some or other example processing sketch in Matt Pearson's book and found point wasn't implemented) but stopped when I heard the WebGL layer was being reworked.

yay! go for it!

Any update on this?

Hi @fractalfrenzy (and @kjhollen, I suppose :) )
I've fallen a bit behind on this - wasn't as quick a patch as I'd imagined (required quite a bit more reading through the source, and reading about WebGL, than I'd anticipated - but that probably speaks to the lacunae in my own knowledge than the difficulty of the task itself).

I'm still planning on getting to this - but if anyone else wants to have a go, please feel free.
