Unbind integer textures

[ivanpopelyshev]

All sample types in shaders can have u or i prefix: usampler2D, isamplerCube

I added those types in SAMPLER_TYPES. To ensure that batcher doesn't use sampler of wrong type, and drawcall doesnt crash, TextureSystem unbinds those kind of textures.

Problem: https://www.html5gamedevs.com/topic/46983-mesh-graphics-render-issue/
Spawns error in console: https://www.pixiplayground.com/#/edit/xpLx-ElnpPPPXFJUkxoRa
Doesnt spawn errors: https://www.pixiplayground.com/#/edit/xpLx-ElnpPPPXFJUkxoRa

I'll defer to someone else (@GoodBoyDigital) for the functionality here, but code quality looks fine. Just a few minor comments.

And welcome back @ivanpopelyshev glad to see PRs from you again.

[ShukantPal]

This is a good addition! We should add it to PixiJS Examples.

nice!

Hey guys, seems like something from @ivanpopelyshev's fix is missing. Using v6.0.2 I am still unable to render integer textures along with float textures.

v6.0.2: https://www.pixiplayground.com/#/edit/hMVY0qgOa6lLoNTi_PnEX <-- Not working
@ivanpopelyshev custom build: https://www.pixiplayground.com/#/edit/xpLx-ElnpPPPXFJUkxoRa <-- Works

[bigtimebuddy]

That's my fault. Looks like it never actually got cherry-picked to 6.0.2. Will make sure it's 6.0.3.
