Hotfix/texture2d gather (#876)

* First pass test to see if GatherRed works.

* Add support for generating R_Float32 textures.

* Set default texture format.

* * Alter the texture2d-gather to work with a R_Float32 texture
* Add support for scalar Texture2d types with GatherXXX in stdlib

* Remove some left over commented out test code from texture2d-gather.hlsl
