I haven't seen an email on this list about the problem yet, so I'm 
sending one :)

After updating to the latest version of Visual Studio 2017 (but 
seemingly due to the latest Windows SDK update), I'm getting the 
following deprecation warning when compiling:

warning C4996: 'ID2D1Factory::GetDesktopDpi': Deprecated. Use 
DisplayInformation::LogicalDpi for Windows Store Apps or GetDpiForWindow 
for desktop apps.
c:\progra~2\wi3cf2~1\10\include\100183~1.0\um\d2d1.h(3355): note: see 
declaration of 'ID2D1Factory::GetDesktopDpi'

Since warnings are treated as errors by default, it would be nice to 
have this warning fixed to avoid having to pass 
--disable-warnings-as-errors when configuring.

Trying to look into a fix a bit; It seems that this method for getting 
the DPI can fail anyhow, maybe it should be removed at this point? Or 
alternatively suppress deprecation warnings for this file?
