Allow RG8 format for SkImage created from texture

Using an RGBA8 image for an RG8 texture was causing confusion in the
underlying driver where copyTexSubImage could be disallowed because
of unequal formats between the framebuffer and texture (RG8 vs RGBA8)
while the application was seeing 2 RGBA8 textures. Removing the
workaround is now possible and fixes the issue.

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.
