The polygon conversion algorithm mistakenly stored the stroke width of
filled polygons in an integer variable. As a result, all stroke widths
were rounded down to the next smaller integer mm size. This commit changes
the types in the relevant functions and variables from int to double.

- don't drop subsequent polys when a non-filled primitive is imported 'in between'
- fix missing holes (also related to the interleaving of stroke and filled shapes, depending on the software that wrote the SVG file)

DXF blocks are virtual groups of items.
The insert entity is what actually places all the block contents at a given coordinate.
This should fix importing drawings from professional CAD tools like SolidWorks that will have a good bit of blocks.
* Do not compile dxf old files.
* import gfx, gal mode: make absolute placement working.
* Import gfx in legacy canvas: use it and make interactive placement working
* Take imported line width in account. Ensure DXF line thickness is OK.
* handling empty files in legacy mode.
