Replace BGRA and scale uniforms with a uniform block (#2496)

Browse Source 
* Replace BGRA and scale uniforms with a uniform block

* Setting the data again on program change is no longer needed

* Optimize and resolve some warnings

* Avoid redundant support buffer updates

* Some optimizations to BindBuffers (now inlined)

* Unify render scale arrays
