Was happening when image buffer had cryptomatte pass, which can easily exceed 530 bytes used by the buffer. Now default buffer is bumped to 1K, and also allowed to be heap-allocated when really need bigger buffer. Possible optimization is to allocate buffer once, but in practice those re-allocations will not happen often, so keeping code simpler is not an issue. Just something for a rainy day.
