Subject: [PATCH] Increase initial heap size from 32 to 256

In complex boards with lots of polygons, we were realloc'ing up
to this kind of number anyway, in x2 size steps. Save all the
memcpy'ing by making the heap larger to start with.

My test board still has some requirement for heaps >256, <512,
but the frequency is low.
