As I read the SetWindowPos documentation, SWP_NOZORDER is the correct
flag for keeping the z-order of the window.

We're about to remove the WS_OVERLAPPEDWINDOW style for undecorated

Not only is the client guaranteed a ConfigEvent, but app.Window
can assume that an unsupported decoration change will be corrected
(by a ConfigEvent with Decorated forced to the supported value).

Until now, fallback decorations were only needed for Wayland client-side
decorations. We're about to support app.Decorated(false) one some platforms,
where Window should not fall back to drawing its own decorations.

We're about to enable platform support for switching native
window decorations on and off. However, the Wayland platform
only supports server-side switching of decoration mode, not
(yet) client-side. Thus, don't switch mode even when asked to.

Apparently, there is a rounding error somewhere in the pipeline
from clearing a FBO to downloading its contents on at least one Apple
M1 machine. Tweak the test colors a bit to make it pass.

Before this change, client-side decorations for Wayland were drawn
before client content, which was prevented from drawing over
decorations with a clip. While visually correct, resize handles would't
work as long as client listeners are near the window edges to swallow
pointer input.
This change makes app.Window draw decorations last, fixing resizing
and saves a clipping operation. This is an alternative to the original
fix for #361, commit 20d4bc2.

The xdg_toplevel expects the min/max window size in DP rather
than pixels. The scaling factor would be applied twice because
we supplied pixels that we scaled ourselves, resulting in windows
twice the expected size on HiDPI screens. This bug probably went
for so long without being detected because it only manifests if
you actually set a minimum or maximum size.

Not all wayland compositors advertise the global registry events
in the same order. In particular, river and sway differ in that
sway advertises the data_device_manager before the seat, and river
does it after. This commit updates our code to correctly bind
the data_device so that we can work with the clipboard regardless
of the registry event order.
Special thanks to Isaac Freund (river maintainer) for helping me
find the root of this problem. You can see Isaac's extremely helpful
and detailed analysis here:

This commit alters the method we use to check for valid cache hits
in the text path cache. Previously we stored the entire text.Layout
that was provided when the cache entry was set so that we could ensure
only identical text.Layouts would produce hits (guarding against hash
collisions). This commit instead pulls the glyph IDs for every glyph
in the text.Layout and stores them in the cache. This uses far less
memory and seems to allow cache entries to be GCed after eviction.

When a key.InputOp is focused, keypresses that it does not explicitly
include in its key set should check for ancestor clip areas that are
interested in them. Previously this check only included ancestors of
the final clip area in the hit tree, and could fail to find ancestors
of the focused key.InputOp because they were in a different branch.
This commit also adds a test to lock in the new behavior.
This can likely be made more efficient by adding a rapid way to map
from the focused key tag to its index in the hit tree. I wasn't sure
whether the complexity was warranted, but I'm happy to do that if
it's desired.

A `flake.lock` file pins the versions of packages Gio requires to build.
However, pinning the `libGL` package may result in a runtime incompatibility
between the user space GPU driver and the system GPU driver. The result is
an error such as
glGetDisplay failed: 0x300
I don't know a way to keep the convenience of pinned flake.lock versions
combined with a system-defined `libGL` package version. This change implements
a workaround: exclude `flake.lock` from version control and let the first
use of `flake.nix` auto-create a lock file that (hopefully) is compatible
with the system.

There are no public API that uses f32.Rectangle anymore. Move Rectangle
to an internal package for internal use.

The unit.Value is a struct and thus more inconvenient to use than its
underlying float32 type. In addition, most uses don't need a general
value, but rather a specific unit given by the context. This change
replaces unit.Value with two float32 units, Dp and Sp. It also changes
variables and parameters of unit.Value to a specific unit type matching
the context. That is, unit.Dp everywhere except for text sizes which are
in Sp.
Switching to typed float32s has multiple advantages
- They can be constants:
const touchSlop = unit.Dp(16)
- Casting untyped constants is no longer necessary:
insets := layout.UniformInset(16)
- Calculation with values is natural:
func (s ScrollbarStyle) Width() unit.Dp {
return s.Indicator.MinorWidth + s.Track.MinorPadding + s.Track.MinorPadding
}
The main API change is that calls to gtx.Px must be replaced with either
gtx.Dp or gtx.Sp depending on the unit.

Like the change to op.Offset before this, clip.RRect and UniformRRect
is usually used with integer coordinates. Change to integer coordinates
to eliminate many useless conversions to float32.

op.Offset is a convenience function most often used by layouts. Layouts
usually operate in integer coordinates, and the float32 version of op.Offset
needlessly force conversions from int to float32. This change makes op.Offset
take integer coordinates, to better match its intended use.

Android doesn't distinguish between the arrow keys on a keyboard and the
directional keys on a remote control, so there's no way to move the caret
in an Editor with arrow keys. This change updates the Android port to map
Android's DPAD_* key codes to the arrow key names, fixing caret movement.
The change also updates Editor to only request arrow keys that actually move
the caret, to keep directional focus movement working.

Prior to this change an editor with no content and a zero minimum
constraint would return itself has having width zero. This
prevented users from being able to see the editor when they
moved focus to it, as it could not display its caret. This
simple change ensures that, at minimum, the editor returns
its dimensions to include the width of a caret.
