[gdal-dev] Improving ogr dxf driver spline reader

[Pero Brbora]

Hi,

I would like to improve ogr dxf driver spline reader. I have created  
few test files and found mistakes in source code. Current spline  
reader creates splines only from control points, and then tries to  
recreate knots and sets weights to 1. From my understanding of splines  
they are completely defined with control points, knots and weights -  
and all this data can be read from dxf file.

Is it ok to:
first) submit ticket with description and test files
second) submit pull request which targets autotest part of gdal and  
adds tests which show that current implementation fails
third) submit pull request which targets ogr dxf dxf driver and fixes  
all of the above

Is this correct approach for contributing to gdal?

Thanks, bye
