Fixes some WebGL types

[kungfooman]

First I just wanted to fix this line:

            location = gl.getUniformLocation(glProgram, info.name);

            shaderInput = new ShaderInput(device, info.name, device.pcUniformType[info.type], location);

location is a WebGLUniformLocation, while ShaderInput just treats it as a number. So maybe ShaderInput should at some point also have its own Webgl wrapper? And then it escalated to get the other types right.

After merging this, the docs build process has errors:

Thank you for pointing that out @willeastcott

I traced it a bit and it comes from https://www.npmjs.com/package/catharsis

Testing expression in node:

> catharsis = require("catharsis");
> catharsis.parse("number", {jsdoc: true}); // working example
> catharsis.parse("[number, number]", {jsdoc: true}); // throws this error

Luckily the other pages generate without a problem so far.

I tried this kind of declaring a tuple too: https://stackoverflow.com/questions/64739315/how-to-document-tuple-using-jsdoc

But for some reason that throws the same error (npm run docs)

So I have to see how to make catharsis accept a tuple or just reverting that tuple.
