Each state have tags for three state-dependent elements: background, alarmindicator, motionindicator.
Each element is described by following values:
- color - only for background element with no file value, this color will be applied for background
- flashing - only for background element with no file value. valid values are true or false
- flashcolor - second color for flashing background
- file - name of image file in skin subdirectory (support png,jpg,gif format)
- frames - for animated images define number of frames
- framewidth - width of one frame
- x - on screen horizontal position when image will be placed
- y - on screen vertical position when image will be placed
- transparency - valid values are true or false. True means that pixel with 0,0 coordinates defines transparency color.

Animated image is a normal image that have all farmes placed horizontally one by one. All frames has the same width
described by framewidth value. Number of frames is described by frames value.

Elements movedindicator and notmovedindicator are described by the same values that elements of state.

General element support disablecontrols value (true/false). True means that all standard control (alarm state and
motion indiciator, moved indicator) will be hidden.
