Whats holding ~100% D GUI back?

[rikki cattermole]

For 100% D GUI toolkit, we would need somebody who is knowledgeable on 
Unicode (text layouting e.g. Bidi) and font rasterization. These 
together are many a man year projects and quite massive.

But more realistically with using e.g. FreeType and HarfBuzz:

- Image library (started)
- Event loop (next on my list to do)
- Windowing
- Render pipeline
- Text rendering (part of render pipeline sort of)
- Widget rendering (I'm doing requirements gathering atm)
- Theme management (CSS-like + reloading + widget renderer + text rendering)
- UI automation
- Controls

So yeah, lots of stuff.

We wanted to get something actually working before making an 
announcement (we rely quite heavily on Manu for image library/render 
pipeline parts and he has been busy most of this year).

Our discussions are on Discord.

Here is an old image that I generated from my experimenting with widget 
rendering:
