Hi,

I'm currently writing some fast and flexible font renderers for Allegro. 
However, I have a few questions about some fairly internal stuff. Can 
anybody help?

1. Is using bmp_write_line et al. as fast as using line[] access? If 
   not, what sort of difference is there?

2. Can you call both bmp_write_line and bmp_read_line on the same line   
   of a bitmap at the same time, and read/write from that line? The docs 
   explicitly say you can't do it with different lines, but are unclear  
   when it comes to the same line.

3. I take it that something special has to be done with Mode-X bitmaps?
   If so, is it easy stuff or should I provide a backup renderer which  
   uses get/putpixel()?

Thanks for your help, and bye for now,
