<# .SYNOPSIS Merges assigned options with the default font options for a FIGlet font. .DESCRIPTION This function takes the default font options (`fontOpts`) and merges them with the user-specified options (`options`). It overrides the default horizontal and vertical fitting rules if specified, and updates additional font properties such as `printDirection`, `showHardBlanks`, `width`, and `whitespaceBreak`. .PARAMETER fontOpts A hashtable containing the default font options, including fitting rules and other font properties. .PARAMETER options A hashtable containing user-specified options to override the default font options. These may include: - `horizontalLayout`: Specifies the horizontal layout type. - `verticalLayout`: Specifies the vertical layout type. - `printDirection`: The direction in which the text is printed. - `showHardBlanks`: A flag indicating whether to display hard blanks. - `width`: The maximum width of the text. - `whitespaceBreak`: A flag indicating whether to break lines at whitespace. .EXAMPLE $fontOpts = @{ fittingRules = @{ hLayout = "default" vLayout = "default" } printDirection = 0 showHardBlanks = $true width = 80 whitespaceBreak = $true } $options = @{ horizontalLayout = "fitted" verticalLayout = "controlled smushing" printDirection = 1 showHardBlanks = $false width = 100 } $mergedOpts = Rework-FontOpts -fontOpts $fontOpts -options $options This example merges the user-specified options with the default font options and returns the updated options. .NOTES This function relies on the `Get-HorizontalFittingRules` and `Get-VerticalFittingRules` helper functions to calculate the fitting rules for the specified layouts.
