Subject: The device origin can be set on WinCE, so use it and redefine conversion
X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/1d63de4a455bde7bad81cb34724cb1df3219cd26?ds=inline

The device origin can be set on WinCE, so use it and redefine conversion
macros accordingly.
Also, convert result of calling GetClipBox from logical to
device coordinates since we're dealing with device coordinates at
this point.
