For every pixel, MTLBlendOperation determines how to combine and weight the source fragment values with the destination values. Some blend operations multiply the source values by a source blend factor (SBF), multiply the destination values by a destination blend factor (DBF), and then combine the results using addition or subtraction. Other blend operations use either a minimum or maximum function to determine the result.
Maximum of the source and destination pixel values.
