This reverts commit ea67e5b0b930ebf552bc7dbd678a35ee6a129c39.
Constructing colors using `fromRGBO` should return the same values as the CSS
`rgba()` notation. rgba(0, 0, 255, 0.5) is the same as `#0000ff80`
However `fromRGBO` sometimes creates a color with an off-by-one alpha value:
expect(Color.fromRGBO(0, 0, 255, 0.5), Color(0x800000ff));
Expected: Color:<Color(0x800000ff)>
Actual: Color:<Color(0x7f0000ff)>
If we use `withOpacity` to create the same color, it returns the correct color:
expect(Color.fromRGBO(0, 0, 255, 1).withOpacity(0.5), Color(0x800000ff));
This should also be changed in lib/web_ui/lib/src/ui/painting.dart in a
followup change.
* Introduce `SkiaObject` an object that's backed by Skia C++ objects that need to be explicitly deleted.
* Automatically delete `SkiaObject`s at the end of frame.
* Make `SkPaint` a `SkiaObject`.
Because `SkiaObject`s are deleted at the end of the frame, the object can be reused as many times as necessary within the frame. `SkPaint` in particular is a fairly expensive object. Reusing this object, for example, on `drawRRect` drops the canvas paint time by 30%.
* adding the default text editing strategy
* [DRAFT] Refactoring text editing. Strategy pattern is used to handle different browser/operating system and a11y behaviour. Unit tests are missing. Documentation needs updating.

* fixing chrome/android a11y issue
* [web] Update build_web_compilers to 2.7.1
This was causing problems with the dart compiler location
for web.
The compiler seems to be present in out/host_debug_unopt/dart-sdk/lib/dev_compiler/kernel/amd/dart_sdk.js as opposed to out/host_debug_unopt/dart-sdk/lib/dev_compiler/amd/dart_sdk.js
* also update build_runner
* some logs
* Masking moddifier state for lock keys if the key code is not the same as the modifier. this fixes tab issue happening when numlock/capslock is on.
* removing modifier state for locks
* addresing pr comments'
