Should this use renderContainer.visibleRowsCache and visibleColsCache instead of grid.Rows and grid.cols? If the data is filtered or rows are not visible, won't the calcs will be off?

[PaulL1]

For columns, it's probably OK because I'm using drawnWidth. However, now you mention it I haven't dealt with RTL at all, nor pinned columns. I presume they would have some impact on the scrolling (definitely for RTL, maybe not materially for pinned containers).

For rows it will definitely impact.

In order to implement I need to understand something about render containers I think. How many render containers can there be, and how do I decide which render container to look in for the visible rows/cols cache to do the calculations? I'm assuming that pinned rows/cols would be in a separate render container?
