I'm afraid I didn't fully understand the idea of the patch. I mean, I
understood the basic idea. But why are you assuming, that 2 samples and
3 samples are the smallest possible ramps that can be achieved with
[vline~] and [line~]?
Also I'm not clear, what kind of signal [vline~] and [line~] are
supposed to produce. They don't accept the same message format. [vline~]
takes up to three arguments (<target value>, <ramp time>, <delay>),
while [line~] takes only two (<target values>, <ramp time>). Check the
help file for the specifics.

Anyway, your patch  makes a few things quite clear.

* Changing the blocksize for the [metro] / [metroplus] doesn't matter
* The blocksize doesn't affect [vline~] as long as it is >= 64 samples.
* [line~] schedules ramps only on block boundaries, so when setting high
blocksizes, one might has to wait a long time until it starts the ramp.
