[[ svgpath ]] Don't recalculate scaled width & height if widget dimensions are unchanged

livecodeian · livecodeian · commit f3695e75da59 · 2019-12-16T14:40:50.000Z
This patch reduces the work done by the svgpath widget's OnGeometryChanged
handler by checking first if the width or height of the widget has changed before
recalculating the scaled dimensions of the svg path
