This is a spectacularly short-sighted attitude. I work for a test 
equipment manufacturer, and we are using X on several of our 
instruments. We display multiple oscilloscope and spectrum analyzer 
displays, ideally updating at video rate (>60 Hz). Each trace on such a 
display consists of 500 to 1000 line segments, and there can be multiple 
traces per object - so we are running about 150 THOUSAND line segments a 
second.

You can bet whatever body part you wish WE NEED ACCELERATED LINE DRAWS.

We also do blits (graticules, waveform masks),  rectangle fills (meters 
and bar graphs).

Just because YOU don't need these things does not mean they are not needed.
