Fix: Issue #1475 Texture Compatibility Check methods need to be centralized (#1482)

Browse source 
* Texture Compatibility Check methods need to be centralized #1475

* Fix spacing

* Fix spacing

* Undo removal of .ToString()

* Move isPerfectMatch back to Texture.cs

Rename parameters in TextureCompatibility.cs for consistency

* Add switch from 1474 to TextureCompatibility as requested by mageven.

* Actually add TextureCompatibility changes to the PR (Add DeriveDepthFormat method)

* Alignment corrections + Derive method signature adjustment.

* Removed empty line as erquested

* Remove empty lines

* Remove blank lines, fix alignment

* Fix alignment

* Remove emtpy line
