I can't find any performance benefit to using the GL path and the code renders this trapezoid incorrectly: top: FIXED 29.50 bottom: FIXED 30.00 left top: POINT 0.00, 29.50 left bottom: POINT 0.00, 30.50 right top: POINT -127.50, 29.50 right bottom: POINT 52.50, 30.00 This should render a solid line from 0,30 to 52,30 but draws nothing. The code also uses an area computation for trapezoid coverage which does not conform to the Render specification which requires a specific point sampling technique.

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.
