Subpixel accurate shadow rendering

Shadows are handled different from glyph and outline.  A shadow
is the sum of glyph and outline bitmap; therefore shifting to the
correct subpixel amount before rasterization is out of the question.
Instead, the bitmap is shifted by its subpixel amount after being
built from shadow and glyph.
The bitmap cache was extended for this.
