#6 Graphics objects 2

[Diemo Schwarz]

Now the more complicated stuff:

It would be great if the graphics display objects could
be configured more flexibly.

First of all, as the scroll direction is in the wrong
sense for displaying time, we need to be able to choose
scrolling from right to left.

Second, the zoom x from the matrix display should be
available for the vector display, too, and should be
settable to < 1 for zooming out of large vectors.

Third, the y-axis of the matrix display (but also the
vector disp) should be flippable, to be able to
display frequency (e.g. of fft vectors) in the usual
sense.

The scroll direction and flip could be unified with the
zoom x/y parameters: negative values change the direction.
All of this of course settable by the inspector and by
messages.

Fourth, maybe it would be useful if the vector display
could receive also a bpf, to have an inline bpf display.

Sixth, for the latter, and in general, an auto-zoom
mode would be great that stretches the data to be
displayed to fit the size of the display object (x, y
or both). (This only has sense for a non-scrolling axis.)
