Set an application defined SoProgressIndicator object which will raise an event before and after the rendering task, before and after each subtask (in this case: Texture creation and Geometry creation) and after each step in the subtasks which represents in most cases individual tiles of data.

- SoProgressIndicator::onBeginTask / SoProgressIndicator::onEndTask will be raised only one time per frame : "Rendering".

• SoProgressIndicator::onBeginSubTask / SoProgressIndicator::onEndSubTask will be raised 2 times per frame : "Loading Texture" and "Create Geometry".
• SoProgressIndicator::onEndStep will be raised several times per subtask.

Track loading progression with SoProgressIndicator::onEndStep event of SubTask "Loading Texture":

• NumSteps represents here the number of tiles to load to reach the "stable rendering state".
• NumStepsDone represents here the number of tiles currently loaded since the last NumSteps reset.
• The two numbers are reset when the viewer is moving the camera.

The example VolRend (examples/source/VolumeViz/VolRend) implements a loading progress bar in class EventRaisedProgressBar.

Limitations :

• if SoLDMResourceParameters::maxMainMemory (CPU Mem) is lower than SoLDMResourceParameters::maxTexMemory / SoLDMResourceParameters::max2DTexMemory (GPU mem/GPU mem for slices) the number of steps to reach the "stable rendering state" will be bigger than expected (the progress bar will stop without reaching the end).
• if screen resolution culling is activated (see SoLDMGlobalResourceParameters::setScreenResolutionCulling) the number of steps to reach the "stable rendering state" might be lower than expected (progress bar reaches the end but loading might continue).
• Not yet supported by SoFenceSlice and SoHeighFieldRender.

If set to NULL no events will be raised. Default is NULL.
