Please support scaled text in ExtTextOutW with lpDx

"ExtTextOutW()" accepts a "lpDx" options, which allows to specify a (x,y) shifting distance between glyphs (http://msdn.microsoft.com/en-us/library/windows/desktop/dd162713(v=vs.85).aspx).

A problem raises when this option is used together with the "SetWorldTransform()" function, which allows to scale a context up/down. The shifting distance should be scaled, too, but it isn't, which makes the distance between glyphs incoherent.

Here is a sample to reproduce :

Binary :

Actual result under Win32 : http://www.tarnyko.net/repo/reactos/scaledtext-win32.png
Actual result under ReactOS (buggy !) : http://www.tarnyko.net/repo/reactos/scaledtext-reactos.png

Here is the patch which fixes this :

it's also attached to the bug report.

(What's interesting : it fixes GTK+ under ReactOS. So now you can run GTK+ programs without glitches :
