Add parameter to configure mesh detail

Could be simple &skip=points, when we use only 1 point of every $points of mesh info.
Or it could be &size=pixels, when we try to show "optimal" for this size of screen.
Or?

What's easier to implement? I think the first solution without knowing the code very well.
What would it mean: &skip=2 use only every second point (50%) and &skip=4 use only every fourth point (25%) of mesh size?

[neopaf]

first is easier to implement... but it will add to our client some complexity as it would need to figure out what to pass.
second let our client be simpler... but removes some of control from the client. in client we may decide to roughen mesh further than viewer wanted. and to pass fake screen size would not be very nice.

not sure about good name for parameter. "skip" does not match a bit as in 50% case it skips 1 point ;)
"use_every_nth_of_mesh" is a bit longish.

some idea?

first of all that parameter should be optional.
what about: reduce_mesh=50 (leaves out every second value)?
or divide_mesh=2 ???
