Paint is an argument on most methods of Canvas, and in many uses the Paint
contains only a color. In this case, return the Paint's value to native code
as an int instead of constructing a list of attributes.
This improved run time on a drawRect benchmark by 35%.
We should probably expose this dial to clients eventually, but this patch just
makes our default match Skia's default of not anti-aliasing RRect and Path
clips.
CanvasImageDecoder is instantiated with a callback into a Dart closure.
That closure was holding references to the ImageDecoder and the returned
Image. The circular reference between the ImageDecoder and the callback
prevented the objects from being GCed, resulting in leakage of the image
buffer.
CanvasImageDecoder will now destroy the callback after it is invoked,
thus releasing its handle to the Dart closure.
This patch changes how we lookup native functions from Dart to be more
extensible. This patch paves the way for removing the dart:ui_internals
library.
I left this code along in my uber patch to remove the DOM and CSS, but it's
just as dead. Also, move lone files out of dead directories into more sensible
places.
The NewTextPainter is still disabled by default. A future patch will flip the
flag to enable it.
This patch uses a new approach to writing bindings by encoding data into array
buffers. This approach is more efficient than the existing IDL based approach.
If this works out well, we should convert our other performance-sensitive
interfaces to this approach in future patches.
Instead, we can just concatenate the records together, which means you can view
the generated trace file without post-processing. Also, I've made the trace
file world-readable, so that you can trace a device without needing root
access.
* Remove most of mojo/dart/embedder
* Update roll.py to only import a subset of mojo/dart/embedder
* Add mojo/dart/observatory
* Update mojo_sdk_revision to get fixes to dart_pkg.py
- truncate pixel values to 1dp since there's really no point being told
the Size is 302.98732587287 by 648.28498579187.
- describe more Widgets so that debugDumpApp() is more useful.
- remove bufferValue from ProgressIndicator (cc @hansmuller) since it's
not yet implemented.
- half-hearted toString() for ThemeData. There's no point making a
complete one, since it would cause line-wrap even on big monitors in
debugDumpApp dumps, and you can easily get the actual values from a
debugging if that's the issue.
- flesh out BoxConstraints.toString() so that fully unconstrained and
fully infinite constraints are called out explicitly. I experimented
with adding even more special cases, e.g. calling out unconstrained
widths with fixed heights, etc, but it made the output less readable.
- remove a redundant _updateVariable() in AnimatedContainer (cc
@abarth).
- add more information to RenderView.toString().
Introduce a class that can describe the metrics used in a Positioned
widget, to enable easier manipulation and storage of the values, e.g.
for animation purposes.
