Some optimizations for the gray-raster (raster engine antialiasing).
Increase the size of the initial memory pool (it's anyways free'd later
on) to improve the performance of the rasterizer and also decrease the
chance of re-allocations.
Also, by combining gray_record_cell and gray_find_cell into one
function, as gray_find_cell is only called from the former, we can skip
some unnecessary operations.
Measured performance improvements range from 58 % to 154 % for rounded
rect filling and stroking.
