// Rectangle (usually clip rectangle) in local coordinate system
//
// U grows to the right, v grows up, so normally upLeft < upRight, vpTop > vpBottom
// Upper left corner belongs to the rectangle, lower right corner doesn't.
// That means:
// upRight - upLeft equals dupLength.
// Rectangle that contains one point (0,0) is {0,0,-1,1}.
// Shading rectangle for dnode starting at (u0,v0) is {u0, v0+dvpAscent, u0+dupLen, v0-dvpDescent}
// Note this last line reflects the big LS convention:
// v0+dvpAscent belongs to line, v0-dvpDescent doesn't.
