[cc] Support 2D scales in raster transforms

Before this patch, AxisTransform2d used to store the transform scale as
a single float, and then all the logic was 1D. This produced suboptimal
results for things like 'transform: scale3d(1, 5, 1)'.

This patch changes AxisTransform2d to store the scale as a Vector2dF,
and updates PictureLayerImpl to use 2D logic. Most of the tiling logic
is kept unchanged, using the maximum component of the scale.

Note that the ideal scale continues clamping the maximum scale component
to not be greater than 5 times the minimum one.

Bug: 1119996

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
