cc/ui: Ensure UI resource bitmaps are correctly aligned for uploads.

The GPU service code assumes that all textures uploads made directly
to shared image interface are 4 byte aligned. While this is true for
RGBA resources, which have 4 bytes per pixel, its not the case for
ALPHA_8 resources. A mismatch in the expected size causes the upload
to fail and the service side tears down the GL context.

This change fixes the above by ensuring that UI resource creation code
allocates and initializes the SkBitmaps with a 4 byte alignment.

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.

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.
