COM_execute()

void COM_execute	(	Render *	render,
		RenderData *	render_data,
		Scene *	scene,
		bNodeTree *	node_tree,
		const char *	view_name,
		blender::compositor::RenderContext *	render_context,
		blender::compositor::Profiler *	profiler,
		blender::compositor::OutputTypes	needed_outputs )

The main method that is used to execute the compositor tree. It can be executed during editing (blenkernel/node.cc) or rendering (renderer/pipeline.cc).

Parameters

Rendering	Render instance for GPU context.
render_data	Render data for this composite, this won't always belong to a scene.
node_tree	Reference to the compositor editing tree
rendering	This parameter determines whether the function is called from rendering (true) or editing (false). based on this setting the system will work differently: during rendering only Composite & the File output node will be calculated

NodeOperation.is_output_program(bool rendering) of the specific operations

- during editing all output nodes will be calculated

NodeOperation.is_output_program(bool rendering) of the specific operations

- another quality setting can be used bNodeTree.
  The quality is determined by the bNodeTree fields.
  quality can be modified by the user from within the node panels.

- output nodes can have different priorities in the WorkScheduler.

This is implemented in the COM_execute function.

OCIO_TODO: this options only used in rare cases, namely in output file node, so probably this settings could be passed in a nicer way. should be checked further, probably it'll be also needed for preview generation in display space
