Steps to reproduce the problem:
1. Open any pdf, can reproduce it on https://mozilla.github.io/pdf.js/web/viewer.html
2. Scroll in with ctrl+mouse wheel using a normal mouse, not a touch pad.

Expected behaviour:
It zooms in with small steps. It can for example be the same steps as ctrl+plus.

Behaviour:
It scrolls in and out way to quickly. It jumps in the steps: 10%, 70%, 150%, 300%, 570%, 1000%.
