<div>
<pre>img_filter_2d_nearest and the other image filter functions access the
args->offset property of the img_filter structure which is a pointer without
checking if the value is actually defined. img_filter_2d_ewa(...) creates a
local copy of img_filter, but it never initializes the offset property. When
that local copy of img_filter is passed into min_filter(sp_sview, sp_samp,
&args, &rgba_temp[0][jj]), an access violation occurs when the offset property
is attempted to be read.</pre>
