coord/ops: use full types for is_coord
...
rather than passing the template class we pass the fully specified
template; ie point<3,float> rather than point.
this makes it dramatically easier to use is_coord in foreign code at the
cost of making the library code slightly more verbose. we no longer have
to obtain a typedef for the root coord class somehow.

min/max constraints. account for the source type's range before doing the
comparison.

quaternion: fix incorrect factorisation in as_matrix

One of the terms in m[0][0] and m[1][1] was incorrectly negated from an
incomplete factorisation when I transcribed the formula.
Also reintroduces the axis-rotation tests which inadvertantly had zero
magnitudes.

quaternion: compare test results using sum-of-differences
...
comparison of floating point values is inexact and there isn't an easy
way for providing an ULP delta via the TAP interface. morever, the
general expected error is too large to reliably express in ULPs.
