- Line drawing algorithms: DDA, Midpoint, incremental calculations,
  integer vs floating point algorithms, derivations, slope regions

- Aliasing: Jaggies/Stair-casing, anti-aliasing, resolution increase
  and weighted sampling based on line width

- Clipping: Bit-codes - trivial reject and trivial accept

- Transformations: 2D and 3D, scale/translation matrices, homogeneous
  coordinates, order of operations

- Matrix: multiplication, use in transforms

- Colors: unsigned bytes, floats, RGB
