/** \class SkAnimator
The SkAnimator class decodes an XML stream into a display list. The
display list can be drawn statically as a picture, or can drawn
different elements at different times to form a moving animation.
SkAnimator does not read the system time on its own; it relies on the
caller to pass the current time. The caller can pause, speed up, or
reverse the animation by varying the time passed in.
The XML describing the display list must conform to the schema
described by SkAnimateSchema.xsd.
The XML must contain an <event> element to draw. Usually, it contains
an <event kind="onload" /> block to add some drawing elements to the
display list when the document is first decoded.
Here's an "Hello World" XML sample:
<screenplay>
<event kind="onload" >
<text text="Hello World" y="20" />
</event>
</screenplay>
To read and draw this sample:
// choose one of these two
SkAnimator animator; // declare an animator instance on the stack
// SkAnimator* animator = new SkAnimator() // or one could instantiate the class
// choose one of these three
animator.decodeMemory(buffer, size); // to read from RAM
animator.decodeStream(stream); // to read from a user-defined stream (e.g., a zip file)
animator.decodeURI(filename); // to read from a web location, or from a local text file
// to draw to the current window:
SkCanvas canvas(getBitmap()); // create a canvas
animator.draw(canvas, &paint, 0); // draw the scene
