vg_loaders/svg: set up default focal values for radialGradient 

Since when not specified, focal values same as center points
fx = cx, fy = cy by default

/**
* 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.
