[Grid] Grid performance issues

[Neon4eg]

In current implementation each cell has an rowDataChange event that causes invocation of markForCheck for all grid
If you change data is some row every it's cell calls rowDataChange. But this is not the main issue.

Main problem shows when permanently setting data set to grid and every cell in the grid causes rowDataChange call. So 100 rows with 10 columns makes 1000 calls of rowDataChange.

Thanks for your advice. I know the mtx-grid is not perfect, it should be refactoring with virtual scroll.
