> Increased size of allocation to reduce number of allocation per
> bitmap. Before change the procedure ignored 'alloc_size' parameter
> and always allocated memory chunk according to 'size' parameter.
> As a result, first chunk could be up to 64K and all following are
> limited by line size. For example, for bitmap 1280x1024 there was
> more than 1008 chunks allocated, for bitmap 128x1024 - 897 chunks.
> We change the procedure to use chunk size up to 64K (similar to first
> chunk). This reduces in described examples number of allocation from
> 1008 to 64 and from 897 to 8 respectively.
