[Interest] Qt3D - Uniform value arrays

[Donald Marotzke]

With the help of the Qt3D source code, especially the file uniform.cpp, 
I found out that the type of uniform should be QVariantList for uniform 
value arrays. It should work with arrays of float, all types compound of 
floats as QColor and possibly with all types which have the same byte 
size as float like int.
Unfortunately I can't get it to work. I set a breakpoint in 
UniformValue::fromVariant and saw that my data was copied, but it never 
arrived in the shader. Has anybody used it before or is this a bug?  Btw 
at the moment I'm using Qt 5.8.0 rc.
