GrobFlip v1.0
			    ~~~~~~~~~~~~~
--> S/SX/G/GX

by Robert Tiismus

[Note: Rotation of grobs 90 degrees has always been a challenge; Jim
Donnelly's Tool Library can do it, but it's very slow.  When I ran
across DFLIP and VFLIP, I flipped!  Used in sequence, they can rotate
a grob 90 degrees either direction, almost instantly!  -jkh-]

Ever want to print a GROB wider than your IR printer can handle?
Ever need to make a mirror image or rotation of a grob?
Now you can... and VERY FAST.

  This package consists of two programs:

	DFLIP	Diagonal Flip: flips the GROB on the first stack level
		over the \ diagonal axis

	VFLIP	Vertical Flip: the same thing but ower the horizontal
		axis

In the both cases you end up with mirror image of the original grob.

You can ROTATE a GROB by using them together.

	Examples: ( By using notation DFLIP = 'D' and VFLIP = 'V' )

	DV	rotates GROB counterclockwise by 90 degrees
	VD	rotates clockwise by 90 degrees
	V	mirror image using horizontal mirror
	DVD	mirror image for vertical mirror

BENCHMARKS:
  DFLIP acting on 131x64 GROB ~ 0.33 sec
  VFLIP same conditions       ~ 0.25 sec 

MEMORY:
  DFLIP needs enough memory to make two copies of the grob
  VFLIP needs enough memory to make one copy of the grob

  You can use those programs and distribute freely as long as you are
not charging money for it.
