Hi list,

developing drivers for PLplot is sometimes difficult, since I don't know 
what the expected behavior is for certain situations. Or how the output 
should look like. For interactive drivers so far I always tried to mimic 
the xwin driver, but for Ubuntu 8.04 with Compiz turned on, this driver 
actually behaves not very nice, missing lines and so on.

So, my idea is, that we try to define behavior and look for certain 
situations. Since very likely no single driver will cover all situations 
we could try to have a list of situations and we decide democratic, what 
is the wanted behavior and which driver works like that. To give an example:

Siutation: Running example 14 with the option -drv_opt xxx=1. Is the 
option supposed to be valid for both streams or only for the first opened?
Solution: driver options at the command line should only be valid for 
the first stream.
Reference driver: xwin, wxWidgets

We could gather this infos in the wiki and create therefore an 
"abstract" reference driver. In the future it would be easier to write 
drivers, since there is a reference.

What do you think about that? Apart from that you may think this is a 
good idea - would you as developers also contribute to this list (either 
situations and solutions)?

That doesn't mean that drivers need to behave like the reference, but it 
should be guideline for new drivers.

Thanks,
Werner
