Drop px-cache-resets, failed try at path appends

Comments out the pixel-cache resetting since it doesn't seem we need it
any more to avoid draw oddities?

For `.fast_path` appends, this nearly got it working except the new path
segments are either not being connected correctly (step curve) or not
being drawn in full since the history path (plain line).

Leaving the attempted code commented in for a retry in the future; my
best guesses are that maybe,
- `.connectPath()` call is being done with incorrect segment length
  and/or start point.
- the "appended" data: `appended = array[-append_len-1:slice_to_head]`
  (done inside the formatter) isn't correct (i.e. endpoint handling
  considering a path append) and needs special handling for different
  curve types?
