Selecting one of the sub menu items sorts all frames in The Frame List according to the selected sort method. This menu is only available when the
currently selected Project is a picture list.
Animations are mostly delta encoded and cannot be sorted, even when they are
nonlinear, it would be too difficult to keep track of the different color
palettes etc.
Sort Frames by Name (Normal)
The frames are sorted, case insensitive, by their names.
Sort Frames by Name (Inverse)
The frames are sorted, case insensitive, by their names in the inverse order.
Sort Frames by Size
The frames are sorted by their size. The pictures with the smallest size are
at the top of the frame list, the pictures with the biggest size at the bottom.
