Type Alias: UiGridSizingMode
UiGridSizingMode =
"fixed"|"content"
Defined in: ui/components/layout-group-component.ts:178
How a GridLayoutGroupEcsComponent sizes one axis's columns/rows: 'fixed'
uses cellSize for every column/row, unchanged from the grid's original
behavior; 'content' derives each column's width (or row's height) from
the largest measured preferred size among the cells that land in it - the
same way an HTML <table> auto-sizes its columns.
