* @param obj The photocam object

* This sets the zoom level. 1 will be 1:1 pixel for pixel. 2 will be 2:1
* (that is 2x2 photo pixels will display as 1 on-screen pixel). 4:1 will be
* 4x4 photo pixels as 1 screen pixel, and so on. The @p zoom parameter must
* be greater than 0. It is suggested to stick to powers of 2. (1, 2, 4, 8,
* 16, 32, etc.).
* This sets the zoom level. If @p zoom is 1, it means no zoom. If it's smaller
* than 1, it means zoom in. If it's bigger than 1, it means zoom out. For
* example, @p zoom 1 will be 1:1 pixel for pixel. @p zoom 2 will be 2:1
* (that is 2x2 photo pixels will display as 1 on-screen pixel) which is a zoom
* out. 4:1 will be 4x4 photo pixels as 1 screen pixel, and so on. The @p zoom
* parameter must be greater than 0. It is suggested to stick to powers of 2.
* (1, 2, 4, 8, 16, 32, etc.).
