still having an issue where the first sample on the left side of the screen is always drawn as 0, but its not a huge issue for now

20ms work very smoothly on a 1.2GHz core 2 duo laptop, so it's probably a safe value.

LFP traces are now only drawn in the space since the last buffer update, this reduced cpu load.
Reverted back to the linedraw method because speed is not an issue any more with this fix.
Currently not issuing full redraws when a user uses the scrollbar, only for clicks and mouse wheel messages.

that was introduced trying to fix buffer delays
data looks ok now, and there seem to be no accumulating delays

this should be made automatic or at least user-selectable through the
GUI
