Description Ronald 2019-03-29 11:28:26 EDT 
When moving the mouse over the grid, CPU-usage raises to high level, on my i7 to over 20%. Easy to reproduce using Steema TeeGrid Datasouece demo. Setting rows.alternate.visible can raise CPY to over 40%.

When columns are wide, e.g. as result of automatic width in combination with PostgreSQL varchar datatype (without size specifier, as recommended by Postgres docs), moving the current row by a simple click takes more than a second.

Added Mouse sensitivity control to disable 'following' of Mouse when preferenced.
