SkRecord: increase min block to 512B, remove max.
When we added the 64K allocation cap, the bots showed we took a perf hit
on some large .skps like desk_pokemonwiki.skp, despite not seeing a local
effect. I'm still not seeing that locally, but I'd like to try removing the cap on
the bots to see what happens. For big monolithic pictures, really packing into
memory tightly is probably not as important as it is for tiny ones.
Similarly, we're probably being too cautious about making tiny allocations.
Today we start at 16 bytes, which isn't really enough to record anything.
Even the smallest picture, say,
save
clipRect
drawRect
restore
requires ~200 bytes, so we might as well move our minimum block size up
near there.
I don't know if 16 bytes is too small to start for GrTextStrikes, so I've left the
behavior the same (though the max is still gone).
Local recording performance is neutral-to-positive:
