Flipped and slanted groups keep their look when a template is opened. A group that was
flipped horizontally or vertically, or slanted, opened unflipped and unslanted, and in another
place, although the print PDF drew it as it was saved. It now opens flipped and slanted, where it
was, in the editor and in page previews alike, so the editor and the print agree again.
Typograph developers notes
TYP-1324: the canvas pin moves from ca70274 to 5b8afe7, the merge of canvas #246, nothing
else in the range. canvas's loader reads a group's flip_horizontal, flip_vertical and shear
before adopt_saved_box() (init_element_new() and the legacy initElement()), and
build_remote_element() leaves those to the loader. canvas-service moves its pin the same day.
