DESCRIPTION

The variable can be set to the following values:

• "0": Use the default line drawing method (Bresenham's line algorithm)

• "1": Use the driver point API using Bresenham's line algorithm (correct,
draws many points)

• "2": Use the driver line API (occasionally misses line endpoints based on
hardware driver quirks

This hint should be set before creating a renderer.
