// Technographics.pptx presentation only contains Blank and Custom layout types.
// But layout slides with Custom types has different slide names,
// like "Title", "Title and Content", etc. And it is possible to use these
// names for layout slide selection.
// Also it is possible to use the set of placeholder shape types. For example,
// Title slide should have only Title pleceholder type, etc.
