Should we allocate the standard_properties field by heap_alloc()

or use "struct d2d_property standard_properties[D2D1_PROPERTY_MAX_INPUTS - D2D1_PROPERTY_CLSID + 1];"

or just remove this field?

Does it means like we should use something like this:

struct d2d_effect
    {
        ....
        const struct d2d_info *info;
    }

I submit a new patch set which makes min_inputs and max_inputs "alive".

I am planning to submit a V2 version of this patch set after that patch set is accepted.
