Oops, i should better care for sending

In the code to set MaxTextureLevels in the Rage128 and Radeon drivers,
4 bytes/texel is assumed when calculating for the max texture size. If we
always convert to 2 bytes/texel for a 16bpp screen when choosing texture
formats, shouldn't that be factored into the calculation? So we'd use
mach64S
