It may end up being nicer to use two separate loops for this.

It would return 2 for the Composite effect, and 1 for the other two effects.
I'm not sure if there would be other value for builtin effects that we have not tested.

It means the count of input index which is out of bound (index which is greater than, or equal to max_inputs).

It means the count of input index which is out of bound (index which is greater than, or equal to max_inputs).
Also, the bound can beinput_count.
Generally, this variable means the count of input index which is out of bound.
The bound can be max_inputs or input_count.

We might as well store that in effect_tests[] then.

We typically clean up in reverse initialisation order, so factory after inputs.

If we invert the condition above, we can return early and slightly reduce the indentation level. Release() before AddRef() doesn't seem entirely safe above; consider the case that "effect->inputs[index]" holds the only reference to the image, and we're setting the same input image again.

That doesn't generally work; the memory returned by HeapReAlloc() may not be the same as what was originally passed in. More broadly, it's not clear to me that we gain much from avoiding d2d_array_reserve() here.

I need to use HeapReAlloc(HEAP_ZERO_MEMORY) to initialize the newly allocated memory to zero.
Which way is better? HeapReAlloc(HEAP_ZERO_MEMORY) or d2d_array_reserve() + memset(0)?
