/**
@file uemf.c
@brief Functions for manipulating EMF files and structures.
[U_EMR]_set all take data and return a pointer to memory holding the constructed record.
The size of that record is also returned in recsize.
It is also in the second int32 in the record, but may have been byte swapped and so not usable.
If something goes wrong a NULL pointer is returned and recsize is set to 0.
Compile with "U_VALGRIND" defined defined to enable code which lets valgrind check each record for
uninitialized data.
Compile with "SOL8" defined for Solaris 8 or 9 (Sparc).
