- * Specifies the current color buffer for span/pixel writing/reading.
- * buffer indicates which window to write to / read from. Normally,
- * this'll be the buffer currently bound to the context, but it doesn't
- * have to be!
- * bufferBit indicates which color buffer, exactly one of:
- * DD_FRONT_LEFT_BIT - this buffer always exists
- * DD_BACK_LEFT_BIT - when double buffering
- * DD_FRONT_RIGHT_BIT - when using stereo
- * DD_BACK_RIGHT_BIT - when using stereo and double buffering
- * DD_AUXn_BIT - if aux buffers are implemented
