* All ScriptEngines should export as consistent an interface as possible
|
|
* so that the learning curve is limited. In particular, the following
|
|
* API should be made available in the script environment:

|

|
|
* PlasmaApplet - the applet of this plasmoid
|
|
* LoadUserInterface(String uiFile) - loads and returns a given UI file
|
|
* LoadImage - loads an image resource out of the plasmoid's package
|
|
* PlasmaSvg - creates and returns an Svg file
