Replace webpack with rollup

[TrySound]

This reduced the size of minified umd bundle from 56kB to 52kB.
Configurations was combined into multiconfig to simplify maintainment.

Terser is prefered over uglify as more stable package.

[TrySound]

I think we are ready for release.

[stefnotch]

Looks good, I'll merge it after giving @andrevenancio some time to look at it.

[andrevenancio]

Looks pretty good to me. Should we just update the README.md with the different import options we now have?

I assume we still need to specify something along the lines of

import { vec2 } from 'gl-matrix/ejs' ?

Or we dont @TrySound ?

[TrySound]

Users may just import without and suffixes.

import { vec2 } from 'gl-matrix';

Advanced users may look at structure here and import what they need.

import * as vec2 from 'gl-matrix/vec2';

To be honest I'm not ready to work on docs because of lack of time. However this may be achieved after release. New imports may be described in release notes.

[stefnotch]

Ok, I'm merging it then.

[stefnotch]

Just wanted to point out a minor observation:
When simply including dist/gl-matrix.js in your website and not importing it, you now have to include glMatrix. before everything (e.g. glMatrix.vec4.create() instead of vec4.create())

That's definitely a breaking change.

[TrySound]

Hm.. I guess I skipped this part. But anyways polluting window is not good practice.

[stefnotch]

Yeah, I'm quite fine with it. I only noticed it when answering someone's question about gl-matrix, because when testing something, I usually just run it in the browser console.

I suppose I could just run this to work around this minor inconvenience.

window.mat2 = glMatrix.mat2;
window.mat2d = glMatrix.mat2d;
window.mat3 = glMatrix.mat3;
window.mat4 = glMatrix.mat4;
window.quat = glMatrix.quat;
window.quat2 = glMatrix.quat2;
window.vec2 = glMatrix.vec2;
window.vec3 = glMatrix.vec3;
window.vec4 = glMatrix.vec4;

[TrySound]

Or like this

const { mat2, mat2d, mat3, mat4, quat, quat2, vec2, vec3, vec4 } = glMatrix;

[andrevenancio]

Yeah for es5 code I think adding to a glMatrix variable on the window makes sense and its quite a common practise. we avoid window pollution and I think most people are used to it. I suppose we might need to improve documentation with a basic example and I'm happy to pick up that myself at some point soon and do a PR. Looks great @TrySound thanks. Do you also have access to the glmatrix website @stefnotch? Is it worth adding a paragraph mentioning all the module options for more advanced users?

[TrySound]

@stefnotch Could you also publish this prerelease on npm? You may use npm publish --tag=next and the version like 3.0.0-0

Yes, I do. (It's just GitHub pages)

[stefnotch]

@TrySound Regarding publishing it to npm:

npm ERR! This package has been marked as private
npm ERR! Remove the 'private' field from the package.json to publish it.

Do I have to publish every single sub-package or...?

[TrySound]

I mentioned in #343

[stefnotch]

Oh, thank you. I'm sorry for not properly reading it the first time.

I published it to npm now

[TrySound]

Great! Thank you
