Change text vertex order of text to be consistent with regular rendering for backface culling

Increasing access

When rendering rectangles, the backface can be culled by doing

drawingContext.enable(drawingContext.CULL_FACE);
drawingContext.cullFace(drawingContext.FRONT);

This is true for rectangless, planes, cubes, and most objects in general.

However, the one exception I've found is text.
With this having practically no other effect and most programs not getting broken by this change (those complex enough to use those features and get affected would likely use a specific version of p5.js whether via cdn or local package anyways) I believe it's worth it to make the change for programs that can use the performance.

While it'd be preferable for

drawingContext.cullFace(drawingContext.BACK);

to work the way most people using WebGL would use it, I don't believe that would be the best route given that there are likely some programs that already rely on this.

Most appropriate sub-area of p5.js?

Change the order of the vertices so that they're going in the other direction rotationally from any perspective.
