57	* WxH+X+Y Set scaling to W% by H%, and position to X% by Y%.
58	* W and H are percentages of the terminal window size.
59	* X and Y are also percentages; e.g., +50+50 centers
60	* the image in the window.
61	* WxH+X Assumes Y == X
62	* WxH Assumes Y == X == 50 (centers the image)

67	* Adjusting position only :
68	* =+X+Y Set position to X% by Y% (absolute).
69	* =+X Set position to X% by X%.
70	* +X+Y Adjust position horizontally X% and vertically Y%
71	* from current position (relative).
72	* +X Adjust position horizontally X% and vertically X%
73	* from current position.
74	*
75	* Adjusting scale only :
76	* Wx0 Multiply horizontal scaling factor by W%
77	* 0xH Multiply vertical scaling factor by H%
78	* 0x0 No scaling (show image at normal size).
79	*
80	* Pixmap Operations : (should be prepended by a colon)
81	* tile Tile image. Scaling/position modifiers above will affect
82	* the tile size and origin.
83	* propscale When scaling, scale proportionally. That is, maintain the
84	* proper aspect ratio for the image. Any portion of the
85	* background not covered by the image is filled with the
86	* current background color.
87	* hscale Scale horizontally, tile vertically ?
88	* vscale Tile horizontally, scale vertically ?
89	* scale Scale both up and down
90	* auto Same as 100x100+50+50
