837 * DOC: Coordinate handling.
838 *
839 * We are coping with sizes and positions in various coordinates and the
840 * handling of these coordinates is somewhat confusing. It would benefit us
841 * all if we define these coordinates explicitly and clearly. Besides, it's
842 * also helpful to follow the same naming convention for variables
843 * representing values in different coordinates.
844 *
845 * I. Definitions
846 *
847 * - (guest) buffer coordinate: this is the coordinates that the guest will
848 * see. The x/y offsets and width/height specified in commands sent by
849 * guest is basically in buffer coordinate.
850 *
851 * - (host) pixel coordinate: this is the coordinate in pixel level on the
852 * host destop. A window/widget of width 300 in pixel coordinate means it
853 * occupies 300 pixels horizontally.
854 *
855 * - (host) logical window coordinate: the existence of global scaling
856 * factor in desktop level makes this kind of coordinate play a role. It
857 * always holds that (logical window size) * (global scale factor) =
858 * (pixel size).
859 *
860 * - global scale factor: this is specified in desktop level and is
861 * typically invariant during the life cycle of the process. Users with
862 * high-DPI monitors might set this scale, for example, to 2, in order to
863 * make the UI look larger.
864 *
865 * - zooming scale: this can be freely controlled by the QEMU user to zoom
866 * in/out the guest content.
867 *
868 * II. Representation
869 *
870 * We'd like to use consistent representation for variables in different
871 * coordinates:
872 * - buffer coordinate: prefix fb
873 * - pixel coordinate: prefix p
874 * - logical window coordinate: prefix w
875 *
876 * For scales:
877 * - global scale factor: prefix gs
878 * - zooming scale: prefix scale/s
879 *
880 * Example: fbw, pw, ww for width in different coordinates
881 *
882 * III. Equation
883 *
884 * - fbw * gs * scale_x = pw
885 * - pw = gs * ww
886 *
887 * Consequently we have
888 *
889 * - fbw * scale_x = ww
890 *
891 * Example: assuming we are running QEMU on a 3840x2160 screen and have set
892 * global scaling factor to 2, if the guest buffer size is 1920x1080 and the
893 * zooming scale is 0.5, then we have:
894 * - fbw = 1920, fbh = 1080
895 * - pw = 1920, ph = 1080
896 * - ww = 960, wh = 540
897 * A bonus of this configuration is that we can achieve pixel to pixel
898 * presentation of the guest content.
