Should test:

  1. TIFF encoding prediction
  2. PNG prediction
  • None, Sub, Up, Average, Paeth, Combination

Include cases with 1,3,4 color components.

Can assume BitsPerComponent = 8 for now. Support for more BPC will be included in a separate ticket which will include making tests.

Tests for PNG prediction part of #320
Would be good to test cases with overflow too
Still need tests for TIFF prediction
