Describes an overlay template that contains common attributes shared by multiple overlays.
<overlaytemplate
template = "string"
position = "X<int>Y<int>"
size = "X<int>Y<int>"
delay = "seconds"
layer = "positive int"
borderwidth = "positive int"
bordercolor = "string"
timeout = "seconds"
bgcolor = "string"
/>
The same attributes are supported as for <overlay>, except that the template attribute is required for <overlaytemplate>.
The overlay template is defined in an XML file. Each XML file must contain only one template definition.
Once a template is defined, you can refer to it in the template attribute of <overlay>. If the template attribute is specified in both <overlay> and <overlaytemplate>, the attribute in <overlay> overrides the one in <overlaytemplate>.
For more information on text overlay and image overlay, see <overlay>.
