Weird button scaling in decorator

[Starcrasher]

Trying the new Arpaint version, I noticed that 'Tool settings' window has a strange bug in decorator tab.

The button to close the window is of the right size when the window is inactive but too small when the window is active. It seems to be of the right size when you click on it to close the window. It happens only with this window whatever the decorator used.

Perhaps something that shouldn't have been scaled? But, so far, I didn't notice that in another program.

This is on nightly x64 hrev56511 This bug has also been reported as [Artpaint issue 290](​https://github.com/HaikuArchives/ArtPaint/issues/290)
