/*\
* Element.transform
[ method ]
**
* Adds transformation to the element which is separate to other attributes,
* i.e. translation doesn’t change `x` or `y` of the rectange. The format
* of transformation string is similar to the path string syntax:
| "t100,100r30,100,100s2,2,100,100r45s1.5"
* Each letter is a command. There are four commands: `t` is for translate, `r` is for rotate, `s` is for
* scale and `m` is for matrix.
*
* So, the example line above could be read like “translate by 100, 100; rotate 30° around 100, 100; scale twice around 100, 100;
* rotate 45° around centre; scale 1.5 times relative to centre”. As you can see rotate and scale commands have origin
* coordinates as optional parameters, the default is the centre point of the element.
* Matrix accepts six parameters.
> Usage
| var el = paper.rect(10, 20, 300, 200);
| // translate 100, 100, rotate 45°, translate -100, 0
| el.transform("t100,100r45t-100,0");
| // if you want you can append or prepend transformations
| el.transform("...t50,50");
| el.transform("s2...");
| // or even wrap
| el.transform("t50,50...t-50-50");
| // to reset transformation call method with empty string
| el.transform("");
| // to get current value call it without parameters
| console.log(el.transform());
> Parameters
- tstr (string) #optional transformation string
