<# .SYNOPSIS Calculates the maximum vertical smushing distance between two sets of text lines. .DESCRIPTION This function determines the maximum number of overlapping lines (`curDist`) that can be vertically smushed between two sets of text lines (`lines1` and `lines2`) based on the smushing rules defined in the `opts` parameter. It evaluates each pair of overlapping lines using the `Can-VerticalSmush` function and adjusts the distance based on the results ("valid", "invalid", or "end"). .PARAMETER lines1 An array of strings representing the first set of text lines. .PARAMETER lines2 An array of strings representing the second set of text lines. .PARAMETER opts A hashtable containing smushing options, including: - `fittingRules.vLayout`: Specifies the vertical layout type (e.g., Full, Fitted, UniversalSmushing). - Additional smushing rules for evaluating line overlaps. .EXAMPLE $lines1 = @( "Hello", "World" ) $lines2 = @( "Foo", "Bar" ) $opts = @{ fittingRules = @{ vLayout = [LayoutType]::UniversalSmushing } } $maxDist = Get-VerticalSmushDist -lines1 $lines1 -lines2 $lines2 -opts $opts This example calculates the maximum vertical smushing distance between the two sets of text lines. .NOTES This function relies on the `Can-VerticalSmush` helper function to evaluate individual line overlaps. The result is determined based on the smushing rules and the overlap validity.
