b575a1ff1a Fix some synchronization flaws 
- shader: add barrier at the end of each iteration to avoid writing before the reading finished
- cpp: add synchronization between compute and graphics, the image barrier is not enough for the data visibility between different submission

7c34859bb6 Fix incorrect VkDescriptorPoolSize in negativeviewportheight. 
There is assertion fail in negativeviewportheight (AMD GPU). The example create two VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER for descriptorSet, but descriptorCount is one in descriptorPool.

afc1663f85 Fix occlusion query example visual glitch 
In the occlusion query example, uniform buffers containing visibility
flags are only updated when the view changes, and visibility information
is calculated from occlusion queries coming from the previous frame.

This means a quick mouse movement can produce a visual glitch by which
the number of visible fragments becomes zero (and this is correctly
reflected in the UI overlay) but the color of the model remains
unchanged, or vice versa, until the view is changed again with the
mouse.

To fix this, update uniform buffers before preparing every frame as part
of the draw() method.
