Workaround for dimensions sample: AIS_LocalContext::SelectedShape() doesn't take into account TopoDS shape local transformation, and operates with selected interactive transformation.
Performs fast BVH construction using LBVH building approach. Algorithm uses spatial Morton codes to reduce the BVH construction problem to a sorting problem (radix sort -- O(N) complexity). This Linear Bounding Volume Hierarchy (LBVH) builder produces BVH trees of lower quality compared to SAH-based BVH builders but it is over an order of magnitude faster (up to 4M triangles per second).

BVH binned builder is used for different rendering aspects, such as view frustum culling, ray-tracing, and (in future) for selection. It is desirable to improve builder performance. This simple patch decreases BVH building time for 30-35%.

Test case for 0025142: Visualization breaks triangulation on shared solids in composite solid model
Do not clean the triangulation in StdPrs_ShadedShape::Tessellate() and
let the triangulation tool process the sub-shapes properly.
Treat triangulation consistently in all AIS classes (AIS_Shape, AIS_TexturedShape).
The following improvements were implemented:
* two additional allocators were introduced
* Allocator which used WinHeap
* Accumulating memory allocator
* Access to Allocators in lists are provided
* Access optimization in data map (seek and find functions returning reference or pointer to value in one shot)

- Introduce vec4 occColor uniform variable for light-less shaders.
- Introduce float occPointSize uniform variable for marker programs.

0025232: Functionality to create solids from set of shapes
Purpose:
The algorithm is to build solids from set of shapes.
It uses the BOPAlgo_Builder algorithm to intersect the given shapes and build the images
of faces (if needed) and BOPAlgo_BuilderSolid algorithm to build the solids.
Steps of the algorithm:
1. Collect all faces: intersect the shapes if necessary and collect the images of faces,
otherwise just collect the faces to the <myFaces> list.
All faces on this step added twice, with orientation FORWARD and REVERSED;
2. Create bounding box covering all the faces from <myFaces> and create solid box from corner points
of that bounding box (myBBox, mySBox). Add faces from that box to <myFaces>;
3. Build solids using faces from <myFaces> using BOPAlgo_BuilderSolid algorithm;
4. Treat the result: Eliminate solid containig faces from <mySBox>;
5. Fill internal shapes: add internal vertices and edges into created solids;
6. Prepare the history.
Fix for regression.

The tolerance value used in BRepClass3d_SolidClassifier has been increased.
