With the simplification in "LzKernelUtils.rect(..)", rounded corners are
now drawn differently compared to 4.7 (and all previous versions).
Here's an example:
---
<canvas debug="true">
<drawview id="dv">
<handler name="oncontext">
this.clear();
this.rect(100,100,500,500,250);
this.fill();
</handler>
</drawview>
</canvas>
---
Only without your changes, this code draws a perfect circle. I've
attached two files for reference:
- LPP-8745.html: draws a rounded rectangle with the code from [1]
- LPP_8745.as: draws a rounded rectangle with Graphics#drawRoundRect(..) [2]
The previous implementation in LzKernelUtils produces results like
"LPP_8745.as", while the new implementation is rather like "LPP-8745.html".
But I can't say what is the expected behaviour here...

And running the application from above prints the following warning in
swf8-debug:
WARNING @extensions/drawview.lzx≈1213: reference to undefined property

Summary: Add individual corner radius to drawview.rect()
Bugs Fixed: LPP-8745 - Add support for border-radius to view (partial)
Technical Reviewer: ptw
QA Reviewer: hminsky
Details: drawing.lzx - Add example of setting individual corner radius.
LzKernelUtils - Add updated rect() routine that handles individual corner
radius.
drawview - Add additional arguments to rect().
Tests: test/drawing/drawing.lzx shows an orange box with rounded corners that
are all different sizes.
