Comment 2 for bug 959159

thanks for the patch, this looks very interesting!
- there is one case where it behaves unexpectedly. If I start a new drawing and export it immediately, then the default layer will not be printed, regardless of the setting of 'keep only visible layers'
- this may be related to the fact that a layer can be visible in two distinct cases, case 1 (default case) the style attribute does not exist., case 2 (not so common) style attribute has value display:inline
