xrender: add a convenience function #177

Closed dkochmanski closed 3 years ago

dkochmanski commented 3 years ago

Exported symbols are: render-make-color, render-color, render-color-p, render-color-{red,green,blue,alpha}.

This class is similar to xlib:color however it also contains the alpha component. It is used in the function RENDER-FILL-RECTANGLES.

RENDER-FILL-RECTANGLES handles also a sequence as a color for backward compatibility.

Why impose a colour construct on users? There's a reason why they shifted from xlib to xcb.

I remember these headlines: "mass exodus from xlib due to introducing data encapsulation" ;) the old way of using a sequence is still available, this change realizes one of numerous todos in this file.
