Vulkan: Fool-proof usage of GL and VK level indices Using boxed types, this change allows the compiler to catch errors when a level index in one space (e.g. GL) is mistakenly used in another space (e.g. VK). This change uncovered a number of bugs due to such mistakes which are fixed. Mistakes are still possible when the index is explicitly extracted, for example to be given to a Vulkan command, or when it's created, for example when retrieved from gl::ImageIndex::getLevelIndex. Future work can include using gl::LevelIndex in gl::ImageIndex directly to alleviate the latter at least.
