Improve linear texture compatibility rules (#2099)
* Improve linear texture compatibility rules

Fixes an issue where small or width-aligned (rather than byte aligned) textures would fail to create a view of existing data. Creates a copy dependency as size change may be risky.

* Minor cleanup

* Remove Size Change for Copy Depenedencies

The copy to the target (potentially different sized) texture can properly deal with cropping by itself.

* Move StrideAlignment and GobAlignment into Constants
