#1494 - Performance improvements targeted at reducing the number of calculations performed for nested charts (charts using the VictoryStack and VictoryGroup wrappers).
corrects behavior of VictoryContainer so that it only adds aria-labelledby and aria-describedby attributes when there are actually title and / or desc elements that are rendered (controlled by the title and desc props on VictoryContainer
adds a tabIndex prop to all primitive components that Victory renders (i.e. VictoryLabel, Bar etc). This prop may be given as a number or a function of other props
adds a desc prop to all primitive components. This prop may be given as a number or a function of other props
#1375 - Evaluates / calculates some props early so they are available when functional props are being evaluated. Most notably, text is evaluated before any other functional props for VictoryLabel so it may be used to determine things like style, etc.
