* rectangle - Plots a rectangle outline. The line can be solid, dotted or
* dashed.
* fill - Plots a filled rectangle.

* clip - Sets a clip rectangle for subsequent plots.
* text - Plots text. (x,y) is the coordinate of the left hand side of
* the text's baseline. The text is UTF-8 encoded. The colour, c,
* is the colour of the text. Background colour, bg, may be used
* optionally to attempt to provide anti-aliased text without
* screen reads. Font information is provided in the style.
* bitmap - Plots a bitmap image. (x,y) is the coordinate of the top
* left of the image. Width and height give the dimensions the
* image is to be plotted to. (Will be different to the image's
* intrinsic width and height if the image is to be scaled.)
* bitmap_tile - Tiled plot of a bitmap image. (x,y) gives the top left
* coordinate of an explicitly placed tile. From this tile the
* image can repeat in all four directions -- up, down, left and
* right -- to the extents given by the current clip rectangle.
* If repeat_x is true, the image is tiled in the x-dimension,
* otherwise it is not. If repeat_y is true, the image is tiled
* in the y-dimension, otherwise it is not.
* group_start - Start of a group of objects. Used when plotter implements
* export to a vector graphics file format. (Optional.)
* group_end - End of the most recently started group. (Optional.)
