Updated Czech translation
DiaPsRenderer::draw_beziergon (): fix to stroke instead of filling
[substitute] Standard - ZigZagLine: keep points in range
Bug 735303 - Don't create empty groups from VDX

Fixed in the VDX plug-in itself but also on the lib API level
with g_return_val_if_fail (objects != NULL, NULL);
Bug 606377 - Remove static filter list from --filter help string ...

Rather than adding another static string to the dynamic list of export
formats supported add another option. With --list-filters (mentioned
with --help) the list of available filters is created dynamically
fitting the current compilation and configuration.
Implement ShapeRenderer::draw_rounded_rect()

The custom shape module can handle rect with radius for some time. Still
the shape exporter was creating stepwise arc/line shapes with a lot of
superfluous connection points. Now it's just doing the same number of
connection points as the original object (if it was Standard - Box)
custom: fix typos and whitespace usage
custom: restore default to only grow the box with text

Text-fitting was set to ALWAYS but that does not change the behavior
to the better when there is no text.
Make old "Standard - Bus" an alias in sheet, rather than code
Updated Czech translation
Bug 606377 - missing pdf export option in man dia‏

Also updated some other options in the English version of the
manual, e.g. three SVG, VDX, --list-filters ...
Fix some leaks related to parent_list_affected() usage
cgm: add header to Makefile.am (found by make distcheck)
Fix shape.dtd to include rx, ry attributes for rect

found by make distcheck
vdx: write a single page size defintion ...

... Visio Viewer does not care, but LibreOffice does.
Also remove bogus optional attributes from Page tag.
vdx: adapt <ForeignData/> attributes and content

At least LibreOffice 4.2.4.2 is not happy with the padding
after base64 data, not even with the linebreak following. See:
https://bugs.freedesktop.org/show_bug.cgi?id=83275

The change in lib/prop_pixbuf.c to not put a linebreak into
the base64 data will have effect on other output as well,
but the tag directly following should not be a problem
anywhere.
Fix recently observed crash with "UML - Component Feature"

found by make distcheck running test-objects and toggling the
auto-routing via object menu function plus reverting it.

xfig: optimize draw_(ellipse|polygon|rect) to combine stroke and fill

Tested with a modified render-test.dia because the original converted to
.fig make xfig 3.2.5c crash on every linestyle other than solid or dotted.

Also tested via xfig plug-in round-trip. For some reason the new single
objects for ellipse, rect and polygon are still put into a group. But
that's an issue to be tackled in xfig-import.c if at all.
