Fixed duration checks where only the duration aliases were being checked ("w"/"h")
- This fixes a bug with StaveNotes that are instantiated with the duration string "1", articulations would render too high above the note because the stem height was not negated
Fixed the 128th rest glyph's properties
- Bounding box for 128th note rests is fixed, now contains the entire glyph
