/**
* The {@code Shape} class provides definitions of common properties for
* objects that represent some form of geometric shape. These properties
* include:
*
* - The {@link Paint} to be applied to the fillable interior of the
* shape (see {@link #setFill setFill}).
*
- The {@link Paint} to be applied to stroke the outline of the
* shape (see {@link #setStroke setStroke}).
*
- The decorative properties of the stroke, including:
*
* - The width of the border stroke.
*
- Whether the border is drawn as an exterior padding to the edges
* of the shape, as an interior edging that follows the inside of the border,
* or as a wide path that follows along the border straddling it equally
* both inside and outside (see {@link StrokeType}).
*
- Decoration styles for the joins between path segments and the
* unclosed ends of paths.
*
- Dashing attributes.
*
*
* Interaction with coordinate systems
* Most nodes tend to have only integer translations applied to them and
* quite often they are defined using integer coordinates as well. For
* this common case, fills of shapes with straight line edges tend to be
* crisp since they line up with the cracks between pixels that fall on
* integer device coordinates and thus tend to naturally cover entire pixels.
*
* On the other hand, stroking those same shapes can often lead to fuzzy
* outlines because the default stroking attributes specify both that the
* default stroke width is 1.0 coordinates which often maps to exactly 1
* device pixel and also that the stroke should straddle the border of the
* shape, falling half on either side of the border.
* Since the borders in many common shapes tend to fall directly on integer
* coordinates and those integer coordinates often map precisely to integer
* device locations, the borders tend to result in 50% coverage over the
* pixel rows and columns on either side of the border of the shape rather
* than 100% coverage on one or the other. Thus, fills may typically be
* crisp, but strokes are often fuzzy.
*
* Two common solutions to avoid these fuzzy outlines are to use wider
* strokes that cover more pixels completely - typically a stroke width of
* 2.0 will achieve this if there are no scale transforms in effect - or
* to specify either the {@link StrokeType#INSIDE} or {@link StrokeType#OUTSIDE}
* stroke styles - which will bias the default single unit stroke onto one
* of the full pixel rows or columns just inside or outside the border of
* the shape.
* @since JavaFX 2.0

// mxt' = x * mxx + y * mxy + mxt
// myt' = x * myx + y * myy + myt

// mxx' = mxx * width
