1. Fixes the clang warnings noted in a post above, other than those
associated with alignment caused by casting.
2. Fixes some minor rounding errors in both WMF and EMF input/output.
Round trip open/save cycles are conservative for EMF and WMF files
(excluding any features that are not full supported in inkscape or the
target file format, for instance, gradients, which must be emulated.)
3. Fixed a missing break in the input WMF LINETO record handling, which
was falling through into the MOVETO and generating a harmless extra "M"
operation in a path.
4. WMF has no POLYPOLYLINE record. However input that maps into
essentially a polypolyline record in SVG is common, for instance dashed
lines that have been converted to line segments. These end up in SVG as
a series of M L M L draw commands in the path. Earlier each M L pair
was going out as a polyline record, now they go as a series of
MOVETO/LINETO records. The primary reason for this change is that
without this change the behavior described in (2) does not occur.
5. Fixed an issue where polyline and polygon records in some instances
ended up with an extra copy of their last point.

This set of patches does the following:
1. Fixed a typo ( where "+ sizeof()" should have been "* sizeof()")
which caused a memory problem for EMF/WMF files with very large numbers
of hatches.
2. Added support for background mode, background color, and textcolor
in hatches. EMF/WMF files change these parameters but the change may
be silent until many records later. This has the odd effect that a
stroke or fill may be defined (in SVG) and then it is ignored later
and replaced with one with a different background color.
3. Fixed WMF output so that it wasn't adding +1 to the number of pixels
for Width and Height. (Allows WMF files to go through several cycles
of save as, open without changing sizes.)
4. Cleaned up indenting of [ew]mf-{print|inout}.* files, to make
them compliant with the inkscape standard. All indents are (I hope)
now 4*i deep.
5. Added underline/strikeout support for text read from EMF/WMF files.
Inkscape itself cannot currently render this, but it makes it into the
SVG, and it shows up correctly when that SVG is read by Opera.
6. Took out all the "throw" calls, replacing them with g_error(). If
this comes up again in debugging a define can be used to remap the
g_error to temporarily reintroduce the throw so that gdb can catch them.
7. Took out the "%6lf" format changes from patch 11724, retained the
"127" length limit in the same sscanf.
8. Put the C type casts back in, reversing those changes from patch
11724. This is a style issue, and I could not find clear guidance for
which way to go. (Nor a good rationale for keeping the lengthier C++
syntax.) So I reviewed a large swath of other inkscape code to see if
there was a trend and found a very large number of other sections that
were using C style casts instead of the more verbose C++ forms. So I
kept it the way it has been.
9. The locale changes from 11724 were of course retained.

New: WMF import/export
implements WMF (Windows Metafile) read and write. Inkscape previously
supported that through uniconverter, which was not very good with WMF
files. The new version now has a complete wmf-print/wmf-inout
implementation, analogous to the previous emf-print/emf-inout. This
handles images, patterns, and various other goodies to the extent that
WMF does. WMF is a bit primitive, many fields are only 16 bits, so it
even more resolution sapping issues than does EMF. Given the choice,
always use the latter format.

EMF import:
- Fix for EMF files with MODIFYWINDOWTRANSFORM records containing rotations
- Add support for embedded PNG and JPG images
- Fix for PowerPoint patterns
EMF export:
- Rotated images are exported using MODIFYWINDOWTRANSFORM records
- Add output option to allow unrotated output (e.g. for PowerPoint 2003)
- Don't rotate hatch and image fills on export
libTERE:
- Fix bug with misplaced words in LTR text (fix for RTL untested)

EMF import (Adobe Illustrator EMF files):
- workaround for issue with page scaling ('MM_ANISOTROPIC', wrong units)
- fix SETWORLDTRANSFORM operation
- fix libUEMF to support older/shorter EMF header forms
EMF import (general):
- fix import of shapes (rectangles) without borders
- handle EMF bitmap modes where a subsection of the image is extracted
EMF export/import:
- increased size in mm of the reference device by 100X on EMF export
(significant when the dpi is calculated on reading the EMF back in)
- changed dpi calculation:
(sum of pixels ref device)/(sum of millimeter ref device)
