use offsetWidth/Height to confine tooltip

both support fill and textFill, stroke and textStroke in text element for graphic and custom series.

Fix #5777 (exception "unexpected call to method or property access" might be thrown when calling ctx.fill or ctx.stroke after a path whose area size is zero is drawn and ctx.clip() is called and shadowBlur is set)

add Radar indicator can set different text color
