Bug 312723 - Fonts broken on Export to Image and Printing - Don't retrieve actual display DPI, but use default value, as the SVG export should not depend on the the current screen resolution - Don't round font height: avoid that font might be too big and text may get clipped (using a slightly too small font size is almost never a problem) Signed-off-by: Ansgar Radermacher <ansgar.radermacher@cea.fr>
