ozone/wayland: Set opaque/input region for non-rectangular window shape.

In ozone/x11, the region is set to a non-rectangular shape from
GetDefaultWindowMask for the rounded corner of browser frame.
The window region is updated in XWindow::UpdateWindowRegion and
sets in shape of X11 ExtensionManager.

In ozone/wayland, it doesn't get any shape information
from the platform window.

In this CL,
- Introduce PlatformWindowDelegate::GetWindowMaskForWindowShape to get
  the window mask information.
- Create |window_shape_| from window mask for non-rectangular window
  shape.
- Create region from |window_shape_| if it exists and set opaque/input
  region.
- Update |window_shape_| and update opaque/input region

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.
