draw_geometry (new chapter 3) attaches to wrong image format

[tom-leys]

In Chapter 3 Draw geometry begins with the following code (attaching using VK_IMAGE_LAYOUT_GENERAL):

void VulkanEngine::draw_geometry(VkCommandBuffer cmd)
{
	//begin a render pass  connected to our draw image
	VkRenderingAttachmentInfo colorAttachment = vkinit::attachment_info(_drawImage.imageView, nullptr, VK_IMAGE_LAYOUT_GENERAL);

However we just transitioned to VK_IMAGE_LAYOUT_COLOR_ATTACHMENT_OPTIMAL. Surely that's the argument required to attachment_info.

vkutil::transition_image(cmd, _drawImage.image, VK_IMAGE_LAYOUT_GENERAL, VK_IMAGE_LAYOUT_COLOR_ATTACHMENT_OPTIMAL);

draw_geometry(cmd);
