More update changes?? (not sure, just wanted to save this so I can delete the project)

- Update the pixi version to 5.1.4 (cleaned up the pixi fork submodule in the process) ...

- new pixi version already supports float textures
- refactor the 2 window update loops

Fixed shared-font atlases!

- Update PIXI with some fixes for floating point textures ...

- Create the render buffer with format RGBA16F, because 32F doesn't seem to work for some reason
- Restore the proper ImGUI shader
- I fixed the PIXI types, so remove src/types/pixi.js.d.ts

More attempts at making render-to-texture work...

Use EXT_color_buffer_float to support blending from our render texture, using format=RGBA and type=FLOAT ...

Need to update PIXI to support RGBA32F (new build in pixi.js-504.tgz, needed to delete package-lock.json)
Still seeing problems with the framebuffer (it's complete, but no rendering?)

Bring in the packaged UMD export of pixi.js from our own repo

ImGui 'kind of' works in the PIXI renderer, but it seems scaled (DPI aware now???) and the mouse doesn't work

Fixed the imgui project so we can do a dev (incremental) build and a distribution build

Start prepping for dev SystemJS build

Do all the building with the typescript rollup plugin (and ignore the cache folder for that). Include the node builtins plugin, and update imgui-js to fix the bad module references to imgui-js

Try using rollup with plain es2015 modules (commonjs for bind-imgui)

Try rollup (does it combine files?)

Very simple setup with systemjs. Doesn't load modules, doesn't rollup yet

Test index.html and main.ts file just to load up ImGui. May have to switch the module setup on imgui-js to not use systemjs, and go with something browserify-compatible

Start work on implementing the 7gui exercises with typescript and a webgl IMGUI
