Lesson 7 nitpicks

This is short.

A reference to a `VkImageViewCreateInfo` in a paragraph when the code has `vk::ImageViewCreateInfo`

Sometimes uses `imageViewCreateWindow` and sometimes uses `createInfo`, and like before there is mixing of C API idioms and C++ (e.g. `VK_IMAGE_ASPECT_COLOR_BIT` vs `vk::ImageAspectFlagBits::eColor` which are both used).

Review the Lesson 7 documentation and compare the prose references with the code examples. Check the naming of imageViewCreateWindow versus createInfo and the C API versus C++ forms such as VK_IMAGE_ASPECT_COLOR_BIT and vk::ImageAspectFlagBits::eColor. Consider the open linked pull request when determining whether the inconsistencies are already addressed.
