ttfLabel:setDimensions(CCSizeMake(0, 10))

When the input height value less then the height of perLine and the input width is 0, it will lead to set the mMaxWidth of TextProperty 0 and when createBitmap,it crash.
Another Bug, if the first word width less than designed width ,operate the divideStringWithMaxWidth function will come into endless loop.
