Before, when setting the `zoom_factor`, the website was already
enlarged, but the zoom was ignored when calculating the logical window
size and mouse position, causing an offset between the actual cursor and
selected elements. That is addressed here

Previously, any frames in flight (`requestAnimationFrame`) on web were
not being cancelled (`cancelAnimationFrame`) when `WebRunner::destroy`
was called. If a user called `destroy`, then immediately removed the
canvas from the DOM, eframe could panic with a "failed to find (canvas)
element by id" error message.
This PR changes two things:
- The canvas element is directly referenced everywhere it's needed
instead of being looked up by `canvas_id`[^1]
- The RAF handle is stored in `WebRunner` and `cancelAnimationFrame` is
called on it inside of `WebRunner::destroy`[^2]
[^1]: The WebGL/WGPU backends were already holding onto the canvas (and
associated GPU context), so the change is just converting all the
`get_element_by_id` lookups to retrieve the canvas from the web runner
handle.
[^2]: There is only ever one frame in flight, so we store it directly as
a scalar field.

* Closes <https://github.com/emilk/egui/issues/4144>
Update modifier state from web mouse events. This allows modifiers to be
correctly updated when the window is not in focus but the mouse is still
moving over the window.
# What's New
* eframe: Added `App::raw_input_hook` allows for the manipulation or
filtering of raw input events
A filter applied to raw input before [`Self::update`]
This allows for the manipulation or filtering of input events before
they are processed by egui.
This can be used to exclude specific keyboard shortcuts, mouse events,
etc.
Additionally, it can be used to add custom keyboard or mouse events
generated by a virtual keyboard.
* examples: Added an example to demonstrates how to implement a custom
virtual keyboard.
[eframe-custom-keypad.webm](https://github.com/emilk/egui/assets/1274171/a9dc8e34-2c35-4172-b7ef-41010b794fb8)
Raw mouse movement is unaccelerated and unclamped by screen boundaries,
and does not relate to any position on the screen.
It is useful in certain situations such as draggable values and 3D
cameras, where screen position does not matter.
https://github.com/emilk/egui/assets/1700581/1400e6a6-0573-41b9-99a1-a9cd305aa1a3
Added `Event::MouseMoved` for integrations to supply raw mouse movement.
Added `Response:drag_motion` to get the raw mouse movement, but will
fall back to delta in case the integration does not supply it.
Nothing should be breaking, but third-party integrations that can send
`Event::MouseMoved` should be updated to do so.
Based on #1614 but updated to the current version, and with better
fallback behaviour.
* Closes#1611
* Supersedes #1614
After merging PR #4036, build errors occurred in eframe-related
applications:

Workspace dependencies can be annoying.
If you don't set them to `default-features=false`, then you cannot opt
out of their default features anywhere else, and get warnings if you
try.
So you set `default-features=false`, and then you need to manually opt
in to the default features everywhere else.
Or, as in my case, don't.
I don't have the energy to do this tonight, so I'll just revert.
This should help slightly with CPU/GPU parallelism when vsync is on.
I also return the time spent on vsync, which can help users figure out
how much CPU wall-time was used on non-vsync stuff
Addition for <https://github.com/emilk/egui/pull/3847>
In previous one i only fixed crash occurring with Wgpu backend. This
fixes crash with Glow backend as well.
I only tested this change with android so most things i changed are
behind ```#[cfg(target_os = "android")]```.
Both fixes are dirty thought. As
<https://github.com/emilk/egui/pull/3172> says that "The root viewport
is the original viewport, and cannot be closed without closing the
application.". So they break rules i guess? But i can't think about
better solution for now.
Closes <https://github.com/emilk/egui/issues/3861>.
This makes all `wgpu` features opt-in for `egui-wgpu` users.
For `eframe`, I opted to enable some `wgpu` features so users can still
use `eframe` without having to also opt-in to extra ewgpu features
(eframe is batteries-included).
