/**
* The visual which renders an animated image
*
- * The following property is essential
+ * One of the following properties is mandatory
+ *
+ * | %Property Name | Type |
+ * |------------------- |-------------------|
+ * | url | STRING |
+ * | urls | ARRAY of STRING |
+ *
+ * The remaining properties are optional
+ * | pixelArea | VECTOR4 |
+ * | wrapModeU | INTEGER OR STRING |
+ * | wrapModeV | INTEGER OR STRING |
+ * | cacheSize | INTEGER |
+ * | batchSize | INTEGER |
+ * | frameDelay | INTEGER |
+ *
+ * pixelArea is a rectangular area.
+ * In its Vector4 value, the first two elements indicate the top-left position of the area,
+ * and the last two elements are the area width and height respectively.
+ * If not specified, the default value is [0.0, 0.0, 1.0, 1.0], i.e. the entire area of the image.
*
- * | %Property Name | Type |
- * |--------------------------|------------------|
- * | url | STRING |
+ * wrapModeU and wrapModeV separately decide how the texture should be sampled when the u and v coordinate exceeds the range of 0.0 to 1.0.
+ * Its value should be one of the following wrap mode:
+ * "DEFAULT"
+ * "CLAMP_TO_EDGE"
+ * "REPEAT"
+ * "MIRRORED_REPEAT"
*
+ * cacheSize is used with multiple images - it determines how many images are kept pre-loaded
+ * batchSize is used with multiple images - it determines how many images to load on each frame
+ * frameDelay is used with multiple images - it is the number of milliseconds between each frame
