/**
* 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.
