ED JOYSTICK IMAGE
-----------------

This is an almost complete rewriting of the stock SynthEdit Joystick Image with more features:

-Pin Always Grasp (bool):
 if set, allows moving the joystick without need to click on the knob directly (a click in the joystick
 rectangle area is enough), and without having the knob forcibly under the mouse pointer (similar to the
 standard Jump to Mouse option, but the knob won't jump to the mouse pointer)

-Min and Max X and Y constrains (float, 0/1):
 allow to limit joystick freedom of movement along both axes by specifing minima and maxima.
 By specifying a same Min and Max value for one axis, obviously you will limit movement along the other axis.

-Unlike the original Joystick Image, the joystick will always move stuck to the mouse pointer (unless the
 pointer is outside the boundaries, or the CTRL key for fine adjusting is pressed, or the option Always Grasp
 is set of course)

-ARGB Colors for the background gradient (Top and Bottom) can be specified as the usual HEX strings
 (eg. FF000000 is solid black, 80006090 is transparent light blue.) By specifying 0 for both values (which
 means alpha channels zero too) the background will be completely transparent

-The amount of movement scaling when pressing CTRL key can be specified by the CTRL Scaling Factor float pin
 as a fraction of 1 (default: 0.1)

-Subpixel movement (which may cause a "blurry" image at non integer pixel positions) can be enabled
 (as with the stock joystick, default) or disabled by the Subpixel Motion option

-When you keep dragging the joystick image even once it reached the gadget boundaries and you invert
 the dragging direction, the Imm Dir Chg (Immediate Direction Change) option will decide whether the
 image shall move immediately (delta-driven, as with the stock joystick, default) or will wait for the
 mouse pointer to cross the boundaries again

NOTE: the CTRL key works only inside Panel View (and in the final VST) but NOT in Structure View (as for SE 1.4)

NOTE: the Compact version is identical but has no settings pins exposed
