TSOTF_ROTATE may be combined only with SOTF_XOFFSET and SOTF_YOFFSET. In
addition, no other values may be combined with SOTF_NOTRANSFORM.
The transformation equation follows.
x' = Origin.x + (xScale * (x-Origin.x)) + (xSkew*(y-Origin.y)) + xOffset
y' = Origin.y + (yScale * (y-Origin.y)) + (ySkew*(x-Origin.x)) + yOffset
