Keyboard height is now treated as a view inset, which could be used to
shrink the content area of the app as is done in the Material Scaffold,
rather than padding, which is used to indicate content areas where user
interaction should be avoided.
This allows for us to start migrating framework classes (notably
Scaffold) to use window.viewInsets.bottom to get the keyboard height.
Once framework updates have landed, we will land an engine patch to
expose the iOS bottom safe area inset as padding.
This change is already landed for Android.

* Call the ICU bidi API to divide the text into LTR/RTL runs and merge
them with the styled runs defined by the application
* Maintain a list of glyph positions sorted by the order of the corresponding
code units in the text, as well as a list of glyphs sorted by x/y coordinates
in the layout
Previously, we failed to clear/update the mark text range on updates
from the framework. This resulted in a crash if the incoming text value
was shorter than the current mark range when iOS attempts to extract the
mark range substring from the text.

Overlooked this case when I previously removed linear blending. MakeS32 creates a surface with a color space attached (triggering the linear blending behavior). MakeN32 creates a legacy surface (no color space), which matches what the other backend bindings do (including the GL surface factory, and the raster cache).
* Use the VM-specific wrapper for the kernel front-end to support VM-specific kernel transformations.
* Also, pass a flag to distinguish AOT mode from JIT mode to enable whole-program optimizations.
* Added Windows support for libtxt in order to build flutter_tester.exe.
Relatively minor changes were needed to get libtxt building on Windows
(missing/incompatiable headers, the odd syscall, path separators, etc.).
Windows doesn't render text in the same way as other platforms, so some tests
that checked for specific pixel offsets are disabled.
Window.viewInsets is the set of window-relative insets that describe the
area of the window that an application may want to treat as effectively
reducing the size of the content. Typically this is due to system UI
that fully obscures underlying content, such as the keyboard.
This area differs from padding in that padding is the set of insets that
describe the area of the window that may be partially (or fully)
obscured by system UI or physical intrusions into the view area (e.g.
iPhone X sensor housing, status bar, or the iPhone X home indicator
widget).
This patch does not yet enable the iOS bottom edge safe area. Once the
framework has been updated to use viewInsets for bottom-edge occlusions
(today, the keyboard), the bottom safe area will be enabled and
framework patches that depend on it, landed.
* Run frontend server from temp directory to force absolute URIs in Kernel file.
* Create special directory to cwd into to avoid conflicts with app sources in temp folder
* Make variable final
As we anyway always recommend to set the target_os to android.
Also if you happen to not set the target_os to android it messes up the licenses script output.
* Move texture registry ownership to platform view
This enables the texture registry to survive activity pause on Android.
* Remove debug info
* Formatted
* Set texture registry on initial rasterizer
* Remove unneccessary std::move
If Progress is instantiated with a max of 0, throw immediately to avoid
a divide-by-zero later in toString(). This typically happens if the tool
recurses over an empty top-level component, which can happen when a
component is moved around in the repo and the developer hasn't cleaned
up old empty directories from their git client.
