Summary0010064: Some information is not copied from Graphic3d_Aspectxxxx to graphic group
DescriptionThe following code in Compute() method of an interactive object leads to
graphic data loss (this problem has been detected while developing a custom
interactive object for MTWZ company):

...
Handle(Graphic3d_AspectFillArea3d) aFill = new
Graphic3d_AspectFillArea3d();
aFill->SetTextureMapOn();
aFill->SetTextureMap( aTexture );
aCurrentGroup->SetPrimitivesAspect( aFill );
...

In this example, information about texture data is not copied properly into
Graphic3d_Group. aFill variable is destroyed at the end of Compute() like any
other local variable. Therefore, texture information is lost, and the texture
is not displayed as expected.
At the same time, other graphic attributes are copied properly (colors, etc.).

A workaround for this problem is to store all newly created aspects in the
object's drawer. However, this is rather tricky, and forgetting about this
workaround results in programming errors which are very difficult to find.

It is proposed to analyze all SetPrimitivesAspect() methods of Graphic3d_Group
and implement correct copying of all data from the aspects.
