From: Eric Pouech eric.pouech@gmail.com
Starting with Win10, height of multiline edit controls no longer seems to be hardwired to a multiple of the font height (when larger than font height).
- Adapt the tests accordingly (detecting how to compute the expected height of a control). - Extend the ranges of the tested heights.
Note: - there may be another way to detect the model for height computation. - the range of heights tested stem from internal testing and is larger than existing testing. It could be reduced as a range, or picking values from a fixed set of values (if needed).
