Reverse depth & 32F buffer format

Browse source 
-Adds reversed depth projection model, dramatically increasing depth buffer effective resolution.
-Adds 32F depth 8U stencil format GFXFormatD32FS8X24 (following DX naming conventions). Note this is a 64-bit format, and likely not suitable for mobile platforms. Revert to GFXFormatD24S8 in renderManager.tscript for mobile & "ancient" platforms.
-Corrects alignment of texture type details array.
