A few changes were required:
* `LinearGradient(LinearGradient)` as enum variant unfortunately
won't compile because the cbindgen generated constructor
function (`LinearGradient()`) will try to also instantiate the
variant type inside (`LinearGradient`) and that won't find the type
but the function itself and error out. So the inner type is now
called `LinearGradientBrush`.
* The same name dance was required for `Color`, where the enum variant
instead is called `SolidColor`
* `BrushInner` was removed in favor of just `Brush`. The nicer Rust
API will be the public variant, and for cbindgen we can just put
the generated enum into an internal namespace, like we do for
Resource for example
* A `NoBrush` variant was added. Maybe that name could be improved?
This intends to provide a configurable rectangular "drop shadow". The
API is modeled after CSS/HTML5 Canvas where the element can be "bound"
to an existing rectangular shape (geometry and radius), the offset can
be used to place the shadow and color and blur configure the shadow.
The shadow's color fades into transparent.
TODO (in subsequent changes):
* Documentation
* Qt implementation
This will give a nicer API to expose to .60. If the struct weren't
repr(C) then the booleans would be nicely packed, but alas that's not
happening. On the other hand we're not keeping many instances of them
around.
Fold CharacterInput into KeyPressed/KeyReleased and store the "key" as a string.
Also, instead of exposing the KeyCode we're encoding special characters
into the string.
This allows creating multiple windows for example, and it will allow for
showing windows in those tests that require a mapped window.
As a bonus, the run() function on generated components is not consuming
anymore.
As discussed, don't use the persistent context approach for single
shot timers but store the callback directly in the global object
and "delete" it afterwards.
