Hi everybody,
    some days ago I stumbled upon vcl Rectangle SvStream >> and << 
operators (gen.cxx). Their implementation handles the case that the 
stream is compressed as COMPRESSMODE_FULL (and can surely be improved). 
For better understanding I opengrok'ed this COMPRESSMODE_FULL and it 
turns out to be used in just 7 [1] files (1 for definition, 2 just set 
it and the remaining 4 use it for selecting I/O implementation).
Regarding I/O implementations, all of them can be improved but I think 
that that of Polygon is also broken. I was planning to clean/fix these, 
but the main question, due to this limited use, is if this feature is 
really used/needed or can be completely removed. Any idea?

Thanks for any hint
