Function resolveExportDownloadName

resolveExportDownloadName(
    sourceName: string | undefined,
    extension: string,
    fallbackBaseName?: string,
): string
Builds a browser download file name from a drawing name.

The first export keeps the drawing base name (for example floor-plan.svg). Subsequent exports with the same base name and extension receive numeric suffixes (floor-plan-2.svg, floor-plan-3.svg, …) within the session.
Parameters
- sourceName: string | undefined
  Drawing file name or title.
- extension: string
  Target extension, with or without a leading dot.
- fallbackBaseName: string = 'drawing'
  Base name when sourceName is empty.
Returns string
