(HAL entry #45)

  void HAL_Video_SetBlank(uint HAL_VideoSetBlank(uint powersave)

Use

This is an internal call for OS use only and should not be used by user software. User software should use GraphicsV instead of interacting with the HAL directly.

The HAL is expected to perform any reasonable measures on the video controller to save power (eg. turn off DACs), when the display is assumed not to be required. Blanking is handled by a separate call.

(What does this really mean. What is acceptable and safe for displays?)
