Thank you for investing interest and energy in deciphering the situation I discovered myself in!!! I have picked up on two major points of interest from your discoveries with the lame point being the non non non bodacious microsoft browsers adhering of the negative min-x and min-y values on the viewBox.
The major kewl point was how you statically assigned the transform attribute with the scale and rotate against the patternChild and then invoked the animation as a parameter of the attr specifier!!! Most Excellent work and again much appreciated. Cheers,
Bundy P.S. Although no where near as intuitive as using the percentage transformOrigin algorithm in conjunction with gsap that chrome natively accepts but a most excellent outcome regardless!!!
