Clears the current RenderTarget with transparent pixels. Note that this operation is affected by the current clip rectangle, if set. To clear the entire surface, call setClipRect(null) prior to calling clear().

This is equivalent to calling:

    clear(Color.TRANSPARENT);

Clears the current RenderTarget with the given Color. Note that this operation is affected by the current clip rectangle, if set. To clear the entire surface, call setClipRect(null) prior to calling clear().

Clears the region represented by the given quad with transparent pixels. Note that this operation is affected by the current clip rectangle, if set, as well as the current transform (the quad is specified in user space). Also note that unlike the clear() methods, this method does not attempt to clear the depth buffer.

Set the node bounds for any node that would like to render objects of a different size to self. This is useful for proportional paints, where by definition proportional paint should be stretched across node bounds to which it has been applied. In most cases nodes/shapes are rendered in a single draw call, and if needed bounds can be determined by inspecting object to be drawn. However not all nodes are so simple, NGText for example can have hundreds of Graphics.drawString(...), draw(...), and fill(...) calls per a single NGText.renderContent(). Use: Before making several draw calls from a single node, setNodeBounds(bounds), when complete invalidate nodeBounds by setNodeBounds(null).

Parameters

bounds:RectBounds

should not include node transform

Synchronize, or flush, any outstanding rendering operations to the destination in preparation for some caller potentially reusing or disposing a resource that has been used as the source of a recently invoked rendering operation. This method does not (yet?) guarantee that the actual pixels in the destination will be updated - it simply guarantees that no currently buffered rendering will depend on any texture data included by reference. The typical usage is before a Texture disposal or "return to texture cache pool" operation.
