applets/taskmanager: Fix grid layout for forced multiple rows/columns
In the case of forced multiple rows/columns, to calculate the effective width and height of the TaskList we need to know the exact number of rows and columns, and also the average occupation of those (fractional if some rows are not full)
Forced multiple rows(2) | Multiple rows(2) on low space |
---|---|
BUG: 488702
FIXED-IN: 6.1.1
Note: untested on IOTM or vertical panels, but as it is using common values it should work the same
