Remove movement estimates from pointer location

When pointer location is enabled, a line starting from (0,0) is drawn in
both positive and negative directions. This line is used for "movement
estimates", or predicted future coordinates of pointer location using
extrapolation with polynomials.

It's unclear what it's used for, but it is annoying to see on screen
when pointer location is enabled. It also only shows up on flings
directed to the top left corner or to the bottom right corner. It does
not show up otherwise, so it's likely not working as intended anyways.

Fixes: 111195578
Test: enable pointer location, the flings in different directions to
ensure that the line originating from (0,0) is no longer present.
also try flinging with multiple fingers to ensure that no crashes are
observed and velocities are displayed for each finger.
