It's quite sensible for a host to clamp a port value hinted
'logarithmic' this way. After all, log(0) doesn't compute.
About the 'sample rate' hint: I've removed all references to it from
my own plugins. It just doesn't work as expected in all hosts, and
that's no surprise to anyone who has examined ladspa.h's attempts at
describing its operation. Just do 'logarithmic' instead and clamp in
the plugin code -- not as nice but good enough, and consistent.
