Change scrolling in the Editor track canvas summary area

Browse Source 
Keep scroll distance consistent when scrolling up and down with horizontal
modifier as when scrolling left to right.

Scroll horizonally by half a page so that no sections of the canvas are skipped
when scrolling.

Scroll by half a page rather than a step like when scrolling in the track
canvas area as it is a summary area so larger steps seem acceptable and having
it use the same scroll distance as when scrolling in the track canvas seems
pointless as you would then just scroll in the track canvas area.
