Performance is a secondary issue at this point. I
recognize using a NEC
7220 in bitmap mode is not its strong suite. My hope is that some of the
NEC 7220 graphics primitives can be used later to speed things along.
You'll be OK with so-called "zero width" lines and arcs, where the
device is allowed to be loose with the rasterization rules, but once
you go to specific widths, unless the 7220 adheres to the X protocol
rasterization rules, you won't be able to use the 7220's builtin
primitives.
This was a common problem with matching hardware acceleration to an X
server -- there were often problems with matching the rasterization
rules specified in the X protocol. Wide line primitives, line join
and end cap styles and every pixel touched only once were common
problems.
