Filter Display Buffer, avail or not avail?

[ustk]

I can successfully get the reference to the DisplayBuffer of a filter like for all other DB, but DB.createPath() returns an empty and DB.getReadBuffer() returns a buffer size of 0...

Ok I can sync it to a FilterDisplay floating tile but the path is not great and more important has never been centred with the frequencies and appear off by quite a few pixels...

So having at least the buffer would allow for a better and consistant drawing (even if the values are off in the buffer too, not ideal but...).

Trying to just align/dimension the floating tile with my "EQ node panel" (in wich I draw the freq lines) results in a badly offset curve if I want the frequencies to be aligned, so it's either the freqs or the curve, not really looking pro...

Second point in the favour of the buffer, we would be able to draw the curve with a finer resolution, because that nasty sharp knife edge...
