fix a use-after-free when profiling rasterizer times.

this commit also includes the turbo drawing pool.
the experiment was successful in getting reasonable
drawing times to a fullhd image, but the process
causes glitches when moving the objects around,
which is unacceptable.

it's been commented out for now.
