Picture.ReplaceRedChannelMBS(RedChannel as picture) as picture
Function:
Returns a copy of the picture with the red channel replaced with the red channel of the given picture.
Notes: Returns nil on low memory.

Picture.RotateImageAndMaskMBS(angle as Double, cut as boolean = False) as picture
Function:
Rotates the picture by angle° counter clockwise.
Notes:
Internally uses RotateMBS.
Works with masked and alpha channel pictures, but is faster with masked pictures.
Returns nil on any error.
if cut is true, the image is cut to the original size.

Picture.ScaleImageAndMaskMBS(width as Integer, height as Integer, AntiAlias as boolean=false, YieldTicks as Integer=0) as picture
Function:
Scales the picture to the new size including mask (in case one exists).
Notes:
This is a self made algorithm which produces nice pictures on all platforms.
It is slower than QuickDraw on Mac OS, but nicer than drawpicture on Windows.
Returns nil on low memory or invalid width and height values.
AntiAlias is set to false if width<=self.width or height<=self.height.
If YieldTicks is 0, no time is given to other threads in your application. If it is a value > 0, this time is waited before a thread switch is done. Setting it to 1 will give away control to another thread after 1/60th of a second. We recommend a value of 3 to 5 for a good reponsibility of your application.
Version 19.4 or newer of our plugin includes scaling for pictures with alpha channel.

Example:
Notes:
Threaded parameter specifies how many threads you want to use:
A negative value disables threading, zero will use one thread for each CPU core and a positive number specifies the thread count.
For each color in the source picture the red, blue and green values are used as index (blue+green*256+blue*65536) in the arrays to get the new color value.
The arrays should have 2^24 entries.
You can pass destination picture. If dest is not nil and size matches, the plugin reuses the picture object which increases performance as no new picture is created.
