..., especially as related to line-drawing accuracy. Particular attention to detail concerning chopping of accumulation errors, using a cast from 64 bit to 32 bit strategy, in the interval [1.0,2.0). Individual pixel errors with overlapping polygons or line segments are about one in a billion, but I can't reproduce any errors at the moment by using random number generation with tens of millions of cases. Emphasis not only on correctness, but also on performance for real-world use or hardware implementation.

Ever had the experience of a 8 bit system, having max. 64k memory, using assembler to write effective small programs? This system is an experimental 8 bit, 16 color computer, with a processer similar to Z80, that (on my laptop using linux with NO opengl support) achieves up to 1.2 Million instructions per second and 50 Hz. screen refresh rate. It has a builtin assembler to load assembler programs. There is a rudimentary rom that implements some basic functions like line input, or a system...
