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

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