Adds `Marginf` to fill the previous niche.
This is all in a pursuit to shrink the sizes of often-used structs, to
improve performance (less cache misses, less memcpy:s, etc).

As part of the work on adding a custom `Border` to everything, I want to
make sure that the size of `RectShape`, `Frame` and the future `Border`
is kept small (for performance reasons).
This PR changes the storage of the corner radius of rectangles from four
`f32` (one for each corner) into four `u8`. This mean the corner radius
can only be an integer in the range 0-255 (in ui points). This should be
enough for most people.
If you want to manipulate rounding using `f32`, there is a new
`Roundingf` to fill that niche.
This adds `WidgetType::Image` and correctly sets it in the Image widget.
This allows us to query for images in kittest tests and tells accesskit
that a node is an image.
It also adds `Image::alt_text` to set a text that will be shown if the
image fails to load and will be read via screen readers. This also
allows us to query images by label in kittest.

Adds support for animated WebP images. Used the already existing GIF
implementation as a template for most of it.

This makes it easier to hit the corners.
Previously the corner response-area was covered by the response-areas of
the edges.

An interactive widget should only be marked hovered if a click/drag
would start an interaction with it.
egui 0.30 introduced a feature where a thin interactive widget could be
hit even if it was partially behind a larger interactive widget.
Unfortunately, this introduced a bug where the top widget would still be
marked as hovered, even though a click would go through to the thin
widget below.
This bug was most notacible when trying to reisize a window by dragging
its corner, which often would result in dragging one of its sides
instead.
This PR fixes this bug.

This aligns all rectangles and (horizontal or vertical) line segments to
the physical pixel grid in the `epaint::Tessellator`, making these
shapes appear crisp everywhere.
* Closes https://github.com/emilk/egui/issues/5164
* Closes https://github.com/emilk/egui/issues/3667
This undoes a lot of the explicit, egui-side aligning added in:
* https://github.com/emilk/egui/pull/4943
The new approach has several benefits over the old one:
* It is done automatically by epaint, so it is applied to everything (no
longer opt-in)
* It is applied after any layer transforms (so it always works)
* It makes line segments crisper on high-DPI screens
* All filled rectangles now has sides that end on pixel boundaries

Native is already delayed by a frame because it calls
`handle_viewport_output` -> `egui_winit::process_viewport_commands`
after drawing. On web however, we process input including viewport
commands separately from drawing.
This adds an arbitrary frame delay mechanism for web and then uses this
with 1 frame delay always
When there are multiple layers (e.g. with custom transforms) close to
each other, the hit test code used to only consider widgets in the layer
directly under the mouse. This can make it difficult to hit thin widgets
just on the outside of a transform layer.
This PR fixes that.
It also prioritizes thin widgets, so that if there is both a thin widget
and a thick widget under the mouse cursor, you will always hit the thin
widgets, even if the thin widgets is layered behind the thick one. This
makes it easier to hit thin resize-handles.
In theory this should allow us to make `resize_grab_radius_side` and
`resize_grab_radius_corner` smaller in a future PR, if we want to.
Hey! I am not sure if this is something that's been considered before
and decided against (I couldn't find any PR's or issues).
This change removes the internal profiling macros in library crates and
the `puffin` feature and replaces it with similar functions in the
[profiling](https://github.com/aclysma/profiling) crate. This crate
provides a layer of abstraction over various profiler instrumentation
crates and allows library users to pick their favorite (supported)
profiler.
An additional benefit for puffin users is that dependencies of egui are
included in the instrumentation output too (mainly wgpu which uses the
profiling crate), so more details might be available when profiling.
A breaking change is that instead of using the `puffin` feature on egui,
users that want to profile the crate with puffin instead have to enable
the `profile-with-puffin` feature on the profiling crate. Similarly they
could instead choose to use `profile-with-tracy` etc.
I tried to add a 'tracy' feature to egui_demo_app in order to showcase ,
however the /scripts/check.sh currently breaks on mutually exclusive
features (which this introduces), so I decided against including it for
the initial PR. I'm happy to iterate more on this if there is interest
in taking this PR though.
Screenshot showing the additional info for wgpu now available when using
puffin
