[enhancement] Missing client function for surface resizing

[Daniel van Vugt]

Missing client API for client-initiated interactive resizing (eg: drag on the client-drawn resize handles)

Actually there are two types of client initiated resizing we need to support:

(a) Client specifies new width and height (e.g. video player loaded new file or System Settings switched panel).
(b) Edge resizing for client-drawn decorations (which is closely related to bug 1420334).

(a) Would be something like:
   mir_surface_resize(surface, width, height);

(b) Could be something like:
   mir_surface_move_resize(surface, delta_top, delta_bottom, delta_left, delta_right);
which would solve bug 1420334 also, as you can then say:

void mir_surface_move_by(MirSurface *s, int dx, int dy)
{
    mir_surface_move_resize(s, dy, dy, dx, dx);
}

It's not just interactive. Sometimes a client just changes size by itself (e.g. control centre).

[Chris Halse Rogers (raof)]

Right. *That's* the morph window support bug.

[Daniel van Vugt (vanvugt)]

I'm not sure "morphing" is always the right term.

Our design docs mentioned type morphing -- changing from one style to another. However a surface simply resizing itself usually is not changing its type. e.g. Navigating System Settings, or Totem showing/hiding the playlist/sidebar.

[Alberto Aguirre (albaguirre)]

Right, morphing should refer to type semantics.

Note we need non-interactive re-sizing since Qt and SDL will attempt to resize their surfaces after they are visible and not due to any pointer drag events.

[Daniel van Vugt (vanvugt)]

I'm working on prerequisite stuff for this, and might even complete this part too.

Fix committed into lp:mir at revision None, scheduled for release in mir, milestone 0.13.0

[Daniel van Vugt (vanvugt)]

The solution that landed addresses (a) but not (b). Let's say (b) will be done as part of bug 1420334.

Note to self: I suspect this functionality isn't working properly. Need to write a Mir demo client to take Xmir out of the equation.
