Using Text.NativeRendering results in characters drawn too close to each other with fractional scale factors

On Windows using Text.NativeRendering causes letters to be drawn either too close to or far away from each other in many cases. The same problem doesn't seem to occur with QtRendering.

Steps to reproduce the problem:

1. set a fractional scale factor (e.g. 125%)
2. run the attached application.

The text may also look a bit off if scrolled slowly vertically.
