horizonal resolution (width). In those cases fb_bpp ended up
completely wrong -- as in 6 bytes per pixel or something like
that. Since we already have a way to calculate fb_depth given
the masks and fb_bpp is effectively the same as fb_depth, all
we need to do is make sure fb_bpp is rounded to the next
multiple of the number of bits in a byte -- we assume we can
divide by the number of bits in a byte throughout vt(4).
While here:
- simplify how we calculate fb_depth.
- use fb_bpp instead of fb_depth to calculate fb_stride;
we know we can divide fb_bpp.
- don't limit fb_width and fb_height by VT_FB_DEFAULT_WIDTH
and VT_FB_DEFAULT_HEIGHT (resp.). Those constants have
not relation to the size of the frame buffer.
This at least fixes "lower-resolution" Macs. We're talking
1280x1024 or so. There still is a problem with 27" Macs,
which typically have a horizontal resolution over 2K.
