Frames in Flight Feedback

[ASchuberth]

For the Frames in flight section of the tuorial, I have some feedback for it.

There are changes needed in recordCommandBuffers() as well that doesn't get mentioned now that commandBuffers is a vector.

void recordCommandBuffer(uint32_t imageIndex) {
+		auto &commandBuffer = commandBuffers[frameIndex];
		commandBuffer.begin({});
...
}

As well as in transition_image_layout():

void transition_image_layout(
	    uint32_t                imageIndex,
	    vk::ImageLayout         old_layout,
	    vk::ImageLayout         new_layout,
	    vk::AccessFlags2        src_access_mask,
	    vk::AccessFlags2        dst_access_mask,
	    vk::PipelineStageFlags2 src_stage_mask,
	    vk::PipelineStageFlags2 dst_stage_mask)
	{
		...
		vk::DependencyInfo dependency_info = {
		    .dependencyFlags         = {},
		    .imageMemoryBarrierCount = 1,
		    .pImageMemoryBarriers    = &barrier};
+		commandBuffers[frameIndex].pipelineBarrier2(dependency_info);
	}

This function also has a different naming convention using snake_case instead of camelCase like the other functions.

Lastly, just a very minor issue, the fence member variable gets renamed from drawFence to inFlightFences. Maybe consider naming it inFlightFence in the previous lesson.
