Log Message
Constrain replaced element layout to from-intrinsic aspect ratio if specified
https://bugs.webkit.org/show_bug.cgi?id=128629
Reviewed by Simon Fraser.
Source/WebCore:
First pass at implementing -webkit-aspect-ratio: from-instrinsics;
After RenderReplaced has done layout, attempt to update the
resulting size to match the desired aspect ratio. This step
will only reduce the size of an element, and never below the
minimum dimensions.
Tests: fast/css/aspect-ratio/columns.html
fast/css/aspect-ratio/containers.html
fast/css/aspect-ratio/simple.html
* rendering/RenderImage.cpp:
(WebCore::RenderImage::imageDimensionsChanged): If we get an update
to our intrinsic dimensions, and layout depends on this, trigger
another layout pass.
* rendering/RenderReplaced.cpp:
(WebCore::RenderReplaced::layout): Implement the step described
above.
LayoutTests:
Three new tests that exercise aspect ratio on:
- normal content
- content that is constrained within a parent container
- content in columns (pages)
