layout,widget: transpose Constraints to use image.Points for limits

Instead of

    type Contraints struct {
	    Width, Height Constraint
    }

use

    type Constraints struct {
	    Min, Max image.Point
    }

which leads to simpler use. For example, the Min method is trivally replaced by
the field, and the RigidConstraints constructor is no longer a net win.

API Change. Rewrites:

    gofmt -r 'gtx.Constraints.Min() -> gtx.Constraints.Min'
    gofmt -r 'gtx.Constraints.Width.Min -> gtx.Constraints.Min.X'
    gofmt -r 'gtx.Constraints.Height.Min -> gtx.Constraints.Min.Y'
    gofmt -r 'gtx.Constraints.Height.Max -> gtx.Constraints.Max.Y'
    gofmt -r 'gtx.Constraints.Width.Max -> gtx.Constraints.Max.X'
