            Bug ID: 90794
           Summary: Fix the Linux HiDPI start screen
           Product: LibreOffice
           Version: 4.2.3.3 release
          Hardware: Other
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: UI
          Assignee: libreoffice-bugs at lists.freedesktop.org

LibreOffice looks pretty good on these screens now, but it leaves a bad first
impression with the start bitmap.

Fixing this is platform specific. For Linux, the relevant file is:
http://opengrok.libreoffice.org/xref/core/desktop/unx/source/splashx.c

The first question is how to fetch the DPI. It can't use the
OutputDevice::DPIScaleFactor, so it needs to do something like "xrdb -query" or
borrow some of what Saldisp::Init does:
http://opengrok.libreoffice.org/xref/core/vcl/unx/generic/app/saldisp.cxx#557

The next step is to get a high-res start bitmap, and display it when
appropriate.

The final step is to fix the progress window which displays inside the start
bitmap.

I believe this is an easy hack.
