[bug77]

in opengl primitive operation is filling a triangle

Right. And filling a rectangle is filling two triangles.

so it is not primitive and it is already available. you need to pass 4 points for it, for rectangle you need one point, width and height

The extension was created by Nvidia but the implementation isn't exclusive to it, any other driver can implement this extension

Ok, that makes a little more sense. It's still weird that it took a quarter of a century for someone to figure out they needed something for filling a rectangle, tho

because linux shells never thought of using opengl before for rendering.

This extension needs one whole triangle (3 points). It basically uses the bounding box of the triangle as visible on the screen to define the a 2D rectangle. So it turns a 3D triangle into a 2D rectangle.

It still allows the rectangle to live in 3d space that way.
