[gdal-dev] GSoC 2016

[Dmitry Baryshnikov]

Hi Jürgen,

There is several problems with libdxfrw:
1. The library have GPLv2 license which is incompatible with GDAL X/MIT
2. The library support only DWG from r14 to the last 2003 version
3. This is third party dependency for GDAL.
4. There is already the DXF driver in GDAL.

The GPLv2 is ok for QGIS, but it'll be nice to not duplicate efforts.
The GDAL is used widely in many projects and a DWG driver from GDAL will 
be available there (including QGIS).
During GSoC we plan to create not 100% featured driver (this is 
impossible for such small period), but something close to GDAL DXF driver.

No idea what is best to do now.

Best regards,
     Dmitry
