/**
* \brief A variable controlling how the 2D render API renders lines
*
* This variable can be set to the following values:
* "0" - Use the default line drawing method (Bresenham's line algorithm as of SDL 2.0.20)
* "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, was the default before 2.0.20)
* "3" - Use the driver geometry API (correct, draws thicker diagonal lines)
*
* This variable should be set when the renderer is created.
