// 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}
