increase the rate at which we dispatch events.

Previously, the input dispatch rate was capped by default to 55.
This worked fine for systems with a refresh rate of 55 or lower. But on
devices with a higher frame rate (such as stingray at 60 fps), we do not
receive events as fast as the rendering system wants to redraw the frames, so
we would occasionally miss events between frames, resulting in a visual
stutter during drag operations where the dragged object would essentially
stay still for a frame.

This fix increases the default rate to 90, or 1.5 times the highest typical
refresh rate of our devices.
