Project files and pictures to show problem

In the latest version of TeeChart for VCL (Build 2015.16.150901)
When zooming a ColorGrid when the "CenteredPoints" property is set to true it is possible that on occasions data is missing around the top and right of the ColorGrid.

If the CenteredPoints property is set to false, this does not happen.


I have attached an example c++builder project and pictures to show the error.
Simply load the data ("teechart testdata.txt") and perform a number of random zooms (top to bottom right or bottom to top left) with the "CenteredPoints"
checkbox checked. After a few tries you should see the effect.

This problem is not found in TeeChart version 2013.09.131119
