[Qemu-devel] [PULL 02/12] vl: rename DisplayType to LegacyDisplayType

[Gerd Hoffmann]

qapi DisplayType will replace the current enum.  For the transition both
will coexist though, so rename it so we don't have a name clash.

[Qemu-devel] [PULL 03/12] gtk: add and use DisplayOptions + DisplayGTK

[Gerd Hoffmann]

Add QAPI DisplayType enum, DisplayOptions union and DisplayGTK struct.
Switch gtk configuration to use the qapi type.

Some bookkeeping (fullscreen for example) is done twice now, this is
temporary until more/all UIs are switched over to qapi configuration.

[Qemu-devel] [PULL 11/12] vl: drop display_type variable

[Gerd Hoffmann]

Switch over all leftover users to qapi DisplayType.
Then delete the unused display_type variable.

Add 'default' DisplayType, which isn't an actual display type but
a placeholder for "user didn't specify a display".  It will be replaced
by the DisplayType actually used, which in turn depends on the
DisplayTypes availabel in the particular build.

[Qemu-devel] [PULL 12/12] ui: Reorder vte terminal packing to avoid gtk3 warnings

[Gerd Hoffmann]

From: Jan Kiszka <jan.kiszka@siemens.com>

Fill the terminal box from right to left to avoid

Gtk-WARNING **: Allocating size to GtkScrollbar 0x55f6d54b0200 without
    calling gtk_widget_get_preferred_width/height(). How does the code
    know the size to allocate?
