/**
 * We use OpenGL's texture coordinate generator to automatically
 * map the TexturePaint image to the geometry being rendered.  The
 * generator uses two separate plane equations that take the (x,y)
 * location (in device space) of the fragment being rendered to
 * calculate (u,v) texture coordinates for that fragment:
 *     u = Ax + By + Cz + Dw
 *     v = Ex + Fy + Gz + Hw
 *
 * Since we use a 2D orthographic projection, we can assume that z=0
 * and w=1 for any fragment.  So we need to calculate appropriate
 * values for the plane equation constants (A,B,D) and (E,F,H) such
 * that {u,v}=0 for the top-left of the TexturePaint's anchor
 * rectangle and {u,v}=1 for the bottom-right of the anchor rectangle.
 * We can easily make the texture image repeat for {u,v} values
 * outside the range [0,1] by specifying the GL_REPEAT texture wrap
 * mode.
 *
 * Calculating the plane equation constants is surprisingly simple.
 * We can think of it as an inverse matrix operation that takes
 * device space coordinates and transforms them into user space
 * coordinates that correspond to a location relative to the anchor
 * rectangle.  First, we translate and scale the current user space
 * transform by applying the anchor rectangle bounds.  We then take
 * the inverse of this affine transform.  The rows of the resulting
 * inverse matrix correlate nicely to the plane equation constants
 * we were seeking.
