'wsh' interprets escape sequences, emulating an ANSI terminal, but some of the emulations are quite slow. Especially slow is changing from the normal color to the highlight color. Is there any other way to draw different-colored characters in a 'wsh' window? It doesn't have to be portable, just fast. Similarly, is there any way to move the cursor position other than sending the ANSI escape sequence?

As a follow-up, meant to shame SGI into action (or whatever) I wrote an editor that runs much faster on a $1000 IBM PC clone than on the 4D25, because of the slow IRIS display in wsh. [On PC's, the standard fast display method is to poke each character and its attribute (foreground and background color) into the area of memory that the display board reads to refresh the screen.] The IRIS doesn't have the "text mode" that the PC has, and doesn't work at all the same way, but still there should be a faster way
