ie Depth/Color MSAA have common alignment, but due to different pixel packing (Depth MSS is interleaved, Color MSS is arrayed)
SamplePerAux$line samples are X-major (for Depth), while Y-major (for Color) packed ie For Depth MSAA, Hdownscale *=SamplePerAux$line;
for color MSAA, Vdownscale = Vdownscale; for both, MSAA-samples/SamplePerAux$line times sample shared CCS-size
HAlign: Horizontal Align in pixels
VAlign: Vertical Align in pixels
DAlign: Depth Align in pixels
HAlignxVAlignxDAlign [RT size] occupies one Aux$line
SamplesPerAux$line: Samples sharing CCS; NSamples divisor on MSAA-samples giving multiple (on shared CCS) to cover all samples
HDownscale: width divisor on CCSRTAlign`d width
VDownscale: height divisor on CCSRTAlign`d height
Convention:
(+ve) HDownscale/VDownscale are downscale factors, and used as divisors
(-ve) HDownscale/VDownscale are upscale factors, their absolute value used as multipliers
ie if HDownscale etc is smaller than 1, its reciprocal is stored with -ve sign
