Since https://github.com/emilk/egui/pull/1919 we can continue
the application after closing the native window. It therefore makes
more sense to call `frame.close()` to close the native window,
instead of `frame.quit()`.
* Use correct FBO to output
* custom_3d_three-d web
* Update .gitignore
* Do not free the FBO
* Use three-d 0.13
* ThreeDApp
* Only construct model and camera once
* Clean-up and docs
* Web build instructions
* Remove unused dependencies
* Update Cargo.lock
* Fix build
* More fixes

The `custom_3d_three-d` example does not enable a depth buffer since it is only rendering a triangle. However, if it is used as a starting point for other projects, it is highly likely that a depth buffer is actually needed, therefore I propose to enable it by default.
Also see [this](https://github.com/asny/three-d/issues/268) issue for full context.
* Re-implement PaintCallbacks With Support for WGPU
This makes breaking changes to the PaintCallback system, but makes it
flexible enough to support both the WGPU and glow backends with custom
rendering.
Also adds a WGPU equivalent to the glow demo for custom painting.
* Move examples out of eframe/examples into examples/
Give each example a `Cargo.toml` and `src/main.rs`.
This makes it easier for people to use as templates.
* Update README.md with more deps needed on vanilla Ubuntu
* Install libgtk-3-dev on CI, hoping that will fix something
