DrawBorder() ignores MaxPen?

[AGS]

Hi,

I think that I have encountered a Problem with Intuition Borders and Graphics Library MaxPen. After a call to SetMaxPen() to a lower value than the display depth allows, then drawing borders with DrawBorder(), the borders have still colors of all planes. Is this a bug in my concept or is it OS and is there a workaround for this?

   FUNCTION
	This will instruct the graphics library that the owner of the rastport
	will not be rendering in any colors whose index is >maxpen. If there
	are any speed optimizations which the graphics device can make based
	on this fact (for instance, setting the pixel write mask), they will
	be done.

	Basically this call sets the rastport mask, if this would improve
	speed. On devices where masking would slow things down (like with
	chunky pixels), it will be a no-op.

This mainly says that *you* are responsible to not use pens which are > MaxPen. If you do so anyway, it's your problem.

Thanks for the hint, I have read this twice and thrice already but did not get the point.

Is there a way to be notified when User changes palette settings in prefs?

Add a DOS notify on env:sys/palette.prefs.
