DPI not handled correctly anymore

[blueyed]

The DPI handling appears to have regressed when moving to xcb-xrm in a7922cc.

See #254 (comment) for the initial report, that could be made to work using *.dpi: 176 in xrdb.

thx. will look at it.

[DaveDavenport]

*.dpi might not be valid syntax (https://tronche.com/gui/x/xlib/resource-manager/file-syntax.html)

*dpi: 133 should work

[DaveDavenport]

Yep. Xlib was violating spec.

[Airblader]

On a separate note, it's currently a bad idea to use only *dpi, even if spec-compliant. Some tools and libraries such as xcb-util-cursor and cairo-xcb, which have not yet adopted xcb-util-xrm, do a hard-coded match on Xft.dpi and will not be able to properly read *dpi. So you should probably use

Xft.dpi: 133
*dpi: 133

Of course feel free to report bugs against those projects so they can adopt xcb-util-xrm. :-)
