Summary of the bug:
FFMAX is often used in this scenario:
{{{
original = FFMAX(original , limit);
}}}
If the original equals limit, with the current implementation limit is
copied to original, which is superfluous.
So I suggest to implement FFMAX equivalent to FFMIN.
Current:
{{{
#define FFMAX(a,b) ((a) > (b) ? (a) : (b))
#define FFMIN(a,b) ((a) > (b) ? (b) : (a))
}}}
Proposed:
{{{
#define FFMAX(a,b) ((a) < (b) ? (b) : (a))
#define FFMIN(a,b) ((a) > (b) ? (b) : (a))
}}}
