react-wordcloud is so good because it automatically calulates the max size of font to show all words.

But, it is too slow to loading if maxFontSize of fontSizes options is too bigger. because it recurvely calll draw function to find the optimized max value of fontSize.

So I propose initRender options of ReactWordcloud.

initRender options is drawing tag-cloud when first attempts during caclulate the maxFontSize. I think It's better user experiance than wating loading completed.
