#5139 (in 0.21.0) made a positive Twist angle turn clockwise, but documents saved by earlier releases stored their angles with the other sign and reopened twisted the other way. The document version (FORMAT_VERSION) goes from 1 to 2. Opening a version 1 document negates its Twist angles (in layers, opacity-mask art, Shaper edits, symbols, graph designs, pattern swatches, graphic styles and brush definitions), unless the file is of the current file version and its generator is VectorCraft 0.21.0 or later. The document opens and saves as version 2. A save for an older file version, which only apps before 0.21.0 read, writes a version 1 document with the angles negated back. Graphic style libraries (.vcstyles) go to version 2: a version 1 library's Twist angles are negated when it is read. Readers do not check either version, so older builds open the new files as before.
