Nabla Point cloud compute rasterizer (Recruitment task)

Description

Will add an example with a rasterizer for point clouds done entirely on compute shaders.

TODO list:

The positions buffer currently reports as "No resource" in RenderDoc
Instead of just the depth buffer, a 64-bit visibility buffer should be generated
The visibility buffer should be shaded according to some information about the points in a later pass
Everything needs to be tested

Can one of the admins verify this patch?

Set up a logger/callback for the OpenGL or Vulkan connection, put a breakpoint in there an intercept any errors.

I think the error might be to do with bad buffer binding.

The no resource thing was fixed when I changed to use the IGPUBuffer as a descriptor instead of the IGPUBufferView; But does one of the examples have setting a callback?

ah yeah BufferView is UTB/TBO so samplerBuffer not storage buffer ;)
