Use separate PaintFlags for the spaced tile shader

We would setup the tile shader using the same PaintFlags that we had
(partially) set up for the actual image draw. This meant that we'd draw
the shader picture using the same blend mode, which could easily end up
yielding nothing.

Set up a "fresh" PaintFlags for the tile shader as needed instead, using
only flags relevant for the shader.
