Direct3D requires GPU vertex attribute structs sizes be a multiple
16. A cleanup commit removed an unusued field, and broke that
assumption.

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.

This commit fixes a visual-only bug in the ListStyle that could
make the scrollbar float at the edge of the maximum constraints
when the list did not occupy the full constraints. The list
would still reserve layout space for the scrollbar in the correct
position, but the scrollbar would not be displayed there.

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.

Instead of cmpletely replacing the IME snippet for every update, expand

Before this change, Tab and Shift-Tab would always result in focus

Before this change, every Event would be passed to the focused InputOp
tag, making it impossible to implement, say, program-wide shortcuts.
This change implements key.Event routing similar to how pointer.Events
are routed: every InputOp describes the set of keys it can handle, and
the router use that information to deliver an Event to the matching
handler.
This is an API change, because every InputOp must now include a filter
matching the keys it wants to handle.

Before this change, synthetic events such as scrolling caused by
focus movement would use semantic information to determine potential
receivers. However, there can only be one handler per area so sibling
handlers would not be considered. This change makes the event delivery
traverse the entire tree of handlers, including siblings.
