3 people e486262d3e Divide Slice: one division makes at most 10000 parts (#1020) (#1504) ...

slice.divide clamped each axis to 1..1000 but checked no total, so one
request made up to a million slices, and resolving the slice list
(slices::resolve, used by slice.list and export) is quadratic in the slice
count: about 5e11 rectangle visits at a million.

A division over 10000 parts (100 x 100) is now refused with a bad-params
error before any part is created; the params doc says so. Resolving 10000
slices is about 5e7 visits, and the test lists them in well under a second.

The test refuses 101 x 100, 100 x 101 and 1000 x 1000 with the slices and
history unchanged, then divides 100 x 100 into 10000 parts and lists them.
Before the fix 101 x 100 was accepted (10100 parts).
