* Comment SVG_GRADIENT_FX_FY_PARSED
|
||||
*
|
||||
* if "fx" and "fy" is not specified then they are fx==cx and fy==cx
|
||||
* but we should also be careful when during the parsing it would be
|
||||
* something like <radialGradient fx="0" cx="100" cy="100">
|
||||
* so then fx is 0, but fy is 100
|
||||
*
|
||||
* So we need to check if focal was parsed, if not then set up same as center
|
||||
* point.
|
||||
*
|
||||
* It is required to set those public variables back to zero when parsing new
|
||||
* gradient.
