legend rect isn't recalcualted at TeeCreateBitmap

See the attached project. It comes with images.

There's a Chart with a TBarSeries with 9 values and the legend aligned to the bottom. This legend is drawn in two rows to fit all the values in the chart width.

Then, we export the chart with TeeCreateBitmap and we show the result in a TImage. This TImage is smaller in width than the Chart.

In v2013.08, the chart created with TeeCreateBitmap presented a legend with 3 rows. So the number of rows and columns is recalculated to fit the new size.

In v2013.09 and up, the chart created with TeeCreateBitmap has the same number of rows in the legend, so it doesn't have enough space to fit the legend and its cut.

Fixed.

When calculating the number of legend rows, Chart.Width (the original width) was being used instead of Chart.ChartBounds.Width (the real width when drawing the chart onto the image).
