The bug seems to be in Windows when it upscales an smaller icon for
HiDPI displays. It works fine if we provide a 256x256 size in the
ico files.
Use the new square icons also used on OS X that removes the share badge
and instead has a share icon only for the OK state. This means that we
can also remove 3 icons and release 3 slots in the registry for
overlay icons (only the first few are actually loaded by explorer).
This also adds a script that uses ImageMagick to convert our SVG icons
to Windows ico files. Since ImageMagick seems to have issue doing
proper antialiasing with pixels on the edge of icons, this also
slightly scale the icons to leave 2px on each edge, out of its
logical 128px width.
It was only used on OS X and couldn't be used by the FinderSync
extension since that one runs in a sandbox. So use the same system
to load images in the legacy extension by shipping them in the
extension bundle instead of the owncloud.app bundle.
This is also given that the legacy extension needs padded icons
while the FinderSync one needs unpadded icons.
This uses the new official API to show overlay icons and add our
custom context menu entry instead of hooking directly into the
Finder process and intercept drawind routines.
A dummy desktopclient target is also in the project to allow debugging
directly in Xcode while the official client can be started from the
command line. Otherwise Xcode won't allow attaching to the debugee.
Dummy icon files have been added while we get proper icon produced.
We can't use the old icons since what we use for the legacy shell
integration is already padded according to where the badge should
appear on the full icon.
