Jon Turney ebcea16e71 hw/xwin: A simpleminded attempt at composition
Rather than drawing the window contents from the shadow framebuffer, use
Composite extension redirection to cause the server to maintain a bitmap
image of each top-level X window, and draw the window contents from
that, so that window contents which are occluded in the framebuffer show
correctly in the task bar and task switcher previews.

v2:
Fix incorrect use of memset() found by gcc5

hw/xwin/winshadgdi.c: In function ‘winBltExposedWindowRegionShadowGDI’:
hw/xwin/winshadgdi.c:861:9: warning: ‘memset’ used with constant zero length parameter; this could be due to transposed parameters [-Wmemset-transposed-args]

v3:
Turn on -compositewm by default

v4:
Ignore -swcursor if -compositewm

-swcursor is not compatible with -compositewm (because the window
contents are drawn from an off-screen pixmap, not from the screen
pixmap, where the software cursor will be drawn).

v5:
Update meson.build also
Add -compositewm option to help output
Update CI to install prerequisites

X Server

The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into.

Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders.

For a comprehensive overview of X Server and X Window System, consult the following article: https://en.wikipedia.org/wiki/X_server

All questions regarding this software should be directed at the Xorg mailing list:
