Min. Layer Time Speed Reduction Glitch

[CCS86]

For some reason, when layer time suddenly drops, the first layer isn't speed reduced like it should be:

You can see here that the first small layer is printed at a significantly higher speed than the identically sized layer above it. This causes a layer time of 5 seconds, when 7 seconds minimum is specified.

This is to avoid sudden speed change for just a little layer, when there is a huge one, a little one and then a big one again.
Currently, it can't look at the next one, so i can't really avoid this slower slowdown.
It seems a fair compromise imo.

Hmm, maybe a child setting to allow single layer skipping, or an averaging of X number of layers in that calculation.

I personally don't see why you would use the minimum layer time setting, and then be upset that it slowed down a single layer which fell below the minimum you set.

here, you can see the "zebra" in speeds.

I'll add a setting in the future.
