Rgb565 green width · case 02
Green is quantized to five bits in a six-bit field.
Case contract
Quantize three RGB bytes into RGB565 using high five red bits, high six green bits and high five blue bits.
Why this case matters
A deterministic software graphics stage with explicit channel and coordinate conventions; no hardware, device profile or API behavior is inferred.
