FIXME this ought be used in the rendered mode API as well; it’s currently only used by direct mode. describes all geometries of an ncvisual–both those which are inherent, and those in a given rendering regime. pixy and pixx are the true internal pixel geometry, taken directly from the load (and updated by ncvisual_resize()). cdimy/cdimx are the cell pixel geometry at the time of this call (it can change with a font change, in which case all values other than pixy/pixx are invalidated). rpixy/rpixx are the pixel geometry as handed to the blitter, following any scaling. scaley/scalex are the number of input pixels drawn to full cell; when using NCBLIT_PIXEL, they are equivalent to cdimy/cdimx. rcelly/rcellx are the cell geometry as written by the blitter, following any padding (there is padding whenever rpix{y, x} is not evenly divided by scale{y, x}, and also sometimes for Sixel). maxpixely/maxpixelx are defined only when NCBLIT_PIXEL is used, and specify the largest bitmap that the terminal is willing to accept.
