Re: Optimized cfbimgblt.c

I'm all for replacing my low level functions with existing
functions, since that will reduce the size of FBUI,
plus if people have already written accelerated routines
it could benefit FBUI greatly.

Actually I have taken a look at your code. It's has potential for selling to some embedded vendor. Alot of the stuff you add is indeed missing but
mostly can be implemented with what we already have. For example:

fb_clear is really fb_fillrect with a rop of ROP_CLEAR. This is something I know Petr has been asking for :-) Which I want to implement.

fb_vline is a rectangle with a height of 1.

fb_read_point,fb_point, and fb_hline are really

struct fb_pixmap {
inbuf
outbuf
}

We really need a way to get framebuffer data which you did with fb_getpixels. I plan to expand fb_imageblit to create a image from the framebuffer. I like to see fb_read use this.

Why a copyarea2 ?

I just want to make a tangential comment, call it trivia almost,
but if we wanted to use my in-kernel GUI -- FBUI -- to handle
the graphics during startup, including the penguin image, or
even to handle the virtual console terminal itself or the login
prompt, then I expect that can be done.
