Subject: GDK W32: send a DELETE selection when using LOCAL selection protocol
X-Git-Tag: archive/raspbian/3.24.39-1+rpi1~1^2~65^2~36^2~52^2
X-Git-Url: https://dgit.raspbian.org/%22http://www.example.com/cgi/success/%22http:/www.example.com/cgi/success?a=commitdiff_plain;h=577f1a992e9cf2c2ad6a6310b446541c72e991e9;p=gtk%2B3.0.git

GDK W32: send a DELETE selection when using LOCAL selection protocol

This was not needed before, but now it seems to be necessary for
some reason. The code is just an adjusted copy of the appropriate
piece of the OLE2 protocol code, sending GDK_SELECTION_REQUEST.

The rest is just fixing the fallout, allowing LOCAL protocol to pass
the functions it wasn't supposed to pass before.

Closes #82
