Add an addFace function that adds a face to the current geometry object

Increasing access

This would make is easier to make completely custom 3D objects, by adding a new means of doing so.

Most appropriate sub-area of p5.js?

Feature request details

The function could have two version. addFace(indices), which takes a list of indices for the vertices you want to add. And add addFace(vectors), which takes in a list of vectors and automatically figures out which indices those vectors should be replaced with and extends the internal list of vertices for the geometry if necessary. I really want the latter one because it requires the least thought for me. And it's not too hard to use a JS object to accomplish this, so don't complain to me about it requiring a search through a list. It does not require one. Just use a JS object. Also also, I want to be able to input 4 indices / vectos at a time, and it will automatically sort them and split the quad into 2 triangles. How should they be sorted? I dunno, just pick some arbitrary rule. I just want to be able to use the function.

The requested entry point is a new addFace function on the current WebGL geometry object; no file or test is named in the issue. First clarify the geometry API and how indexed and vector-based inputs should behave. Done would require an agreed behavior for four-vertex faces, including their triangulation, plus tests for the supported input forms.
