/* DIFFERENCES BETWEEN imgs.width, conf.width AND rotate_data.cap_width

* ===========================================================================
* 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.
