feat: Support PIXI v5

[exoego]

Closes #83

I took over PR #79 by @motla, because I really need PIXI5 support.

It seems that build succeeded, then some test fails

large (2048x2048) Error: Error: Error rendering "Basic example":
  WebGL unsupported in this browser, use "pixi.js-legacy" for fallback canvas2d support.
    at /root/project/node_modules/happo-target-firefox/lib/index.js:49:19

It looks like PIXI5 now use WebGL and drop canvas2d by default.

Do you have any idea to resolve this?

[themoonrat]

Some test environments do not have WebGL support.
In v4, PixiJS supported bother canvas and WebGL out of the box
For v5, regular PixiJS supports WebGL, but only the legacy builds includes Canvas support.

Should be a case of switching over unit tests to rely and use pixi-legacy.js rather than pixi.js

[exoego]

Is it OK to switch from pixi.js to pixi.js-legacy ?
Or, is it possible to use pixi.js-legacy only on test ?

[themoonrat]

The only reason it exists as a dev dependency is for the unit tests, I believe, so I think it'll be fine to switch.

[tleunen]

You probably want to update this line too

pixi-multistyle-text/.happo.js

Line 14 in 336bed0

'node_modules/pixi.js/dist/pixi.js',

cc @blurymind Mind taking a look as well? I think you want to keep v4 compatibility for a bit until Gdevelop moves to v5?

We can also decide to only support v5 going forward and release a major version.

[exoego]

OK, now CI is green.

[blurymind]

Feel free to upgrade it 😁 once GD moves to pixi5, we will move to the upgraded version too. This PR will help us do that without much work. We are currently bundling the minified library with the extension, so this PR will not affect GDevelop

Hi guys, can you please push this version to npm?

[tleunen]

I'm going to merge it and release a version.

What's going to happen to Pixi with canvas support? Are they dropping it?

[tleunen]

Looks legit! Thank you @exoego

[blurymind]

@4ian the pixi-multistyle library now supports pixi5, so it wont be a problem when updating GD to 5 :)

[4ian]

Great! We should get started with the migration to Pixi 5 on GDevelop then :)

[Bouh]

Will there be support for bitmapText from pixi v5 ?
