In particular, the right half's should consist of blocks\n+ of the same color for 1/16th active sensor pixel array width. The\n+ least significant bits in the quantized gradient should be copied\n+ from the most significant bits of the smooth gradient. The height of\n+ each bar should always be a multiple of 128.

The generator should be reset at\n+ the beginning of each frame, and thus each subsequent raw frame with\n+ this test pattern should be exactly the same as the last.\n+ - name: TestPatternModeCustom1\n+ value: 5\n+ description: |\n+ The first custom test pattern.
