Oh, I understand!

I/OHRRPGCE(20248): gfx_sdl: screen size is 1280*736
I/OHRRPGCE(20248): gfx_sdl: selected zoom = 3

So SDL_SetVideoMode(0, 0, bitdepth, flags) returns the actual 
resolution, 1280*736 and then allocates a screen of that full size. Then 
select_zoom_automatically finds the biggest zoom that fits within that 
size.

... *testing*

I forced the screen size to 320x200 and zoom to 1, and then recompiled 
with SdlVideoResize=y and it works beautifully on the Nexus 7

Now if we can just figure out a method that works on both old and new 
devices, or a graceful way to pick between the two screen sizing 
methods.
