Fix scaling of x/y for graphic symbols.

Units are in 1/4 km, so need to scale by 0.25. This also requires using
floating point arrays for these variables, which necessitates no longer
directly reading from the ByteBuffer into the variable, but a conversion
from short to float.
Dave Fulker suggested that
slices should have multiple
parts: e.g. [a:b,c:d].
This commit implements that facility.
It turned out be to be tricky because
the one slice per dimension assumption
is embedded pretty deeply in the code.
There may still be places I missed.
