-don't set capabilities at compile time
-since our accelerated putchar() doesn't underline, don't claim so
-remove bogus character range check - fonts are not limited to ASCII
-use rasops_unpack_attr() instead of relying on rasops internals
is found not fully upward compatible to its predecessor. sfbp.c is now
under development.
- Reduce copycols() malfunction, but has still lot of troubles.
to be corrected. Text drawing is now improved significantly, but;
cursor is drawn incorrectly, copycols() trashes a screen, 'standout
(\033[7m)' results in lines reversed entirely until '\033[0m', and
possibly more issues. Not multi-colour, 8bpp only this moment. Costly
write memory barrier instrunctions should be eliminated using framebuffer
address aliasing technique for NetBSD/alpha.
- returned EOPNOTSUPP rather than -1.
- no check for negative offset.
many of these fix potential security problems in these drivers.

the d_mmap cdev routine should be changed to have a prototype like:
paddr_t (*d_mmap) __P((dev_t, off_t, int));
by someone!
bit/pixel format, not planer format. Assign MSB for cursor mask and
LSB for cursor image, where 10 means mask color and 11 for image color.
Image bit order of Bt431 and Bt459 are opposite to MIPS/Alpha processors
while IMS G332 and DC503 (PCC) are indentical.
- Assume that cursor images are 32 pixel padded as ULTRIX/DU ws interface
do. It's natural to X server.
- XXX Vast majority of codes are duplicated between mfb<->tfb and cfb<->sfb.
Code sharing might be achieved in the context of TGA/SFB+ merge.
N.B., Digital UNIX never supports neither PMAG-AA (mfb) nor PMAG-BA (cfb)
for TC Alphas. PMAG-DV (xcfb) is Personal DECstation built in. All should
be good for console, but need much works for cursor/colormap completeness.
