* feat(combobox): implement text wrap for selected text
* chore(changelog): add line to changelog
* feat(combobox-text-wrap): make wrap boolean

- the selected text will now use the maximum available width while still
respecting the spacing and icon coming after it

Closes https://github.com/emilk/egui/issues/2068
Before this PR, the default font, Ubuntu-Light, was ~11% smaller
than it should have been, and the default monospace font, Hack,
was ~14% smaller. This means that setting the font size `12` in egui
would yield smaller text than using that font size in any other app.
Ooops!
The change is that this PR now takes into account the ttf properties
`units_per_em` and `height_unscaled`.
If your egui application has specified you own font sizes or text styles
you will see the text in your application grow
larger, unless you go in and compensate by dividing all font sizes by
~1.21 for Ubuntu-Light/Proportional and ~1.16 for Hack/Monospace,
and with something else if you are using a custom font!
This effects any use of `FontId`, `RichText::size`, etc.
This PR changes the default `Style::text_styles` to compensate,
so the default egui style should look the same before and after this PR.

* Better estimate the plot bounds for generator functions
Avoid infinities, and sample more densely
* Optimize and improve plot auto-bounds logic
* Fix cropping out of the top/bottom of plots during auto-bounds
This is a fix for the behaviour on macOS platforms where any egui app would use the dedicated GPU and consume more power than needed. Not all apps might have dedicated GPU requirements.
* 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.
This provides a better estimate of a typical frametime in reactive mode.
From the docstring of `stable_dt`:
Time since last frame (in seconds), but gracefully handles the first frame after sleeping in reactive mode.
In reactive mode (available in e.g. `eframe`), `egui` only updates when there is new input or something animating.
This can lead to large gaps of time (sleep), leading to large [`Self::unstable_dt`].
If `egui` requested a repaint the previous frame, then `egui` will use
`stable_dt = unstable_dt;`, but if `egui` did not not request a repaint last frame,
then `egui` will assume `unstable_dt` is too large, and will use
`stable_dt = predicted_dt;`.
This means that for the first frame after a sleep,
`stable_dt` will be a prediction of the delta-time until the next frame,
and in all other situations this will be an accurate measurement of time passed
since the previous frame.
Note that a frame can still stall for various reasons, so `stable_dt` can
still be unusually large in some situations.
When animating something, it is recommended that you use something like
`stable_dt.min(0.1)` - this will give you smooth animations when the framerate is good
(even in reactive mode), but will avoid large jumps when framerate is bad,
and will effectively slow down the animation when FPS drops below 10.
When painting a scatter plot we sometimes want to paint hundreds of thousands of points (filled circles) on screen every frame.
In this PR the font texture atlas is pre-populated with some filled circled of various radii. These are then used when painting (small) filled circled, which means A LOT less triangles and vertices are generated for them.
In a new benchmark we can see a 10x speedup in circle tessellation, but the the real benefit comes in the painting of these circles: since we generate a lot less vertices, the backend painter has less to do.
In a real-life scenario with a lot of things being painted (including around 100k points) I saw tessellation go from 35ms -> 7ms and painting go from 45ms -> 1ms. This means the total frame time went from 80ms to 8ms, or a 10x speedup.
