yes. i'm getting the drift. :) it was slow 2 years ago. i was kind of hoping
it'd moved on since then. i started work on using it and found at the time even
1:1 scaled blending was not outperforming client-side software routines. i
halted work on that code pending improvement. :)

hmmm bugger. i'd have expected at least identity checks. i'd also have expected
checks for simple 2d scaling (no rotation) in the transform matrix as this is an
easier case to accelerate - especially in software.
