Updated some JsDoc definitions

[Gaweph]

• Minor fixes to JsDoc comments that are preventing typescript generation
• Added Method overload for applyMatrix() - added support for 4x4

(JsDoc definition are used in the generation of the typescript files @ https://github.com/p5-types/p5.ts used by https://github.com/DefinitelyTyped/DefinitelyTyped)

Rationale:

p5.RendererGL.applyMAtrix(arguments) is called from this method which then expects either 6 or 16 values

p5.RendererGL.prototype.applyMatrix = function(a, b, c, d, e, f) {
  if (arguments.length === 16) { // 4x4 matrix
    p5.Matrix.prototype.apply.apply(this.uMVMatrix, arguments);
  } 
};

@limzykenneth Is there anything further needed for this PR?

[limzykenneth]

It would be great to have a graphic like the one currently used for the 2x3 matrix in the description for the 4x4 matrix as well.

I see what you mean. Are you refering to this page:
https://p5js.org/reference/#/p5/applyMatrix

I shall add a graphic to the 4x4 which will mean that the param descriptions are not needed :)

[Gaweph]

@limzykenneth 4x4 image added. I think this will work fine without any param descriptions, the images highlight what the properties are for :)

Let me know if you think we need anything further on this

[limzykenneth]

I would still prefer the text description to be present.

@limzykenneth OK I think it now has the best of all options. There is an example image for both 6 and 16 array sizes. Each overload has clear description and param names aren't reused so there is no confusion regarding what neds to be passed into each method.

Let me know if you think anything further is needed

[Gaweph]

@limzykenneth Do you ned any further changes on this? Once this PR goes in I can generate the new p5 definitelytyped d.ts definitions

[limzykenneth]

150px width is a bit too small for this matrix. You can preview this using grunt yui:dev.

[limzykenneth]

Almost there, just one more thing.

@limzykenneth
Increased size, you are right, was way too small :)

[Gaweph]

Almost there, just one more thing.

@limzykenneth Ping. Are we happy with this now sir?

[limzykenneth]

Looks good. Thanks!
