BPP on a kobo ? 16? is it?

Is the kobo glo a 16 bpp machine under the hood?

The reason I ask is I am looking to implement SDL dithering on the kindles.

I did try just patching the SDL lib I built using a patch that Niluje dug up but it seems to target 16 bpp blit?

So. Is the device 16bpp by default?

is there a place to go ogle some metrics?

thanks! :2thumbsup
