/* DIFFERENCES BETWEEN imgs.width, conf.width AND rotate_data.cap_width
 * (and the corresponding height values, of course)
 * ===========================================================================
 * Location      Purpose
 * 
 * conf          The values in conf reflect width and height set in the
 *               configuration file. These can be set via http remote control, 
 *               but they are not used internally by Motion, so it won't break
 *               anything. These values are transferred to imgs in vid_start.
 *
 * imgs          The values in imgs are the actual output dimensions. Normally
 *               the output dimensions are the same as the capture dimensions,
 *               but for 90 or 270 degrees rotation, they are not. E.g., if 
 *               you capture at 320x240, and rotate 90 degrees, the output
 *               dimensions are 240x320.
 *               These values are set from the conf values in vid_start, or 
 *               from the first JPEG image in netcam_start. For 90 or 270 
 *               degrees rotation, they are swapped in rotate_init.
 *
 * rotate_data   The values in rotate_data are named cap_width and cap_height,
 *               and contain the capture dimensions. The difference between
 *               capture and output dimensions is explained above.
 *               These values are set in rotate_init.
