Derivatives of Core::Object should be constructed through
ClassName::construct(), to avoid handling ref-counted objects with
refcount zero. Fixing the visibility means that misuses like this are
more difficult.
Previously, we were always getting the full screen(s) bitmap from
the WindowServer and cropping it manually. The `get_screen_bitmap`
function already took in a `crop_region`, so we are now utilizing
that.
The way overlay was drawn is not the correct way to achieve window
transparency in selection mode. With this change, shot window becomes
truely transparent.
* LibGUI: Verify m_window_id is not-zero in set_maximized
Window::set_maximized requires non-zero window id to be a valid call,
i.e. calling Window::show beforehand. A verify statement before the
server call can help developers by hinting correct usage.
* LibGUI: Paint background when the fullscreen window is transparent
The windows in the background are ignored when the window is fullscreen.
However, we still would like to see the background if that window is
transparent.
* Userland: Add ability to capture rectangular region in shot
A click and drag selectable, transparent, fullscreen window is
displayed with the command line argument -r for screenshots.
This enables the shot utility to capture all screens or just one, and
enables the Magnifier application to track the mouse cursor across
multiple screens.
This changes client methods so that they return the IPC response's
return value directly - instead of the response struct - for IPC
methods which only have a single return value.
