/* RAK (Richard Kirk, rak@cre.canon.co.uk) changes 14/7/99
InputStream.skip() looped to check the actual number of
bytes is read.
Big/little-endian options on element length.
Explicit check for each known VR to make mistaken identifications
of explicit VR's less likely.
Variables b1..b4 renamed as b0..b3.
Increment of 4 to offset on (7FE0,0010) tag removed.
Queries on some other unrecognized tags.
Anyone want to claim them?
RAK changes 15/7/99
Bug fix on magic values for explicit VRs with 32-bit lengths.
Various bits of tidying up, including...
'location' incremented on read using getByte() or getString().
simpler debug mode message generation (values no longer reported).
Added z pixel aspect ratio support for multi-slice DICOM volumes.
