1D tile span support for depth/stencil/color/textures

Z and stencil buffers are always tiled, so this fixes
sw access to Z and stencil buffers.  color and textures
are currently linear, but this adds span support when we
implement 1D tiling.

This fixes the text in progs/demos/engine and progs/tests/z*
