Because some uniform variables need to be set for every trapezoid rendering, we can not use vbo to render multi trapezoids one time, which have performance big loss. We now add attributes which contain the same value to bypass the uniform variable problem. The uniform value for one trapezoid will be set to the same value to all the vertex of that trapezoid as an attribute, then in FS, it is still a constant.

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.
