message: Properly initialize VulkanBinder::mDescriptorKey
  * Properly initialize VulkanBinder::mDescriptorKey
  Previously, the contents of mDescriptorKey were not being initialized during VulkanBinder construction. This could leads to bugs, such as getOrCreateDescriptor finding false entries inside the DescriptorKey::uniformBuffers or DescriptorKey::samplers arrays.
  * Spaces instead of tabs
  For shame ;(
