+// We store vertex coordinates and the quad shape in a constant buffer, this is
+// easy to update and allows us to use a single call to set the x, y, w, h of
+// the quad.
+// The QuadDesc and TexCoords both work as follows:
+// The x component is the quad left point, the y component is the top point
+// the z component is the width, and the w component is the height. The quad
+// are specified in viewport coordinates, i.e. { -1.0f, 1.0f, 2.0f, -2.0f }
+// would cover the entire viewport (which runs from <-1.0f, 1.0f> left to right
+// and <-1.0f, 1.0f> -bottom- to top. The TexCoords desc is specified in texture
+// space <0, 1.0f> left to right and top to bottom. The input vertices of the
+// shader stage always form a rectangle from {0, 0} - {1, 1}
