How this works: parallax values configure perceived distance from camera
when it's moving along x and y axes. Assume that zoom is moving the
camera away and scale layers accordingly, with background layers
(furtherst away) changing the least.
New per-ItemGroup (LayerGroup) setting allows to set the new parallax
value independently from the other two. This can be used to do tricks
like on Time Shop zoom correctly or make it feel like the camera is
changing the field of view at the same time as moving in space.
Fix pointer and pointer array variable naming
Huge renaming to match our rules
Used regex: (?!(return|delete)\b)\b\w+ (m_|ms_|g_|gs_|s_)[^a]\w+\[
(?!(return|delete)\b)\b\w+ (?!(m_|ms_|g_|gs_|s_))[^a]\w+\[
Further format static variables
Format almost all pointer names accordingly
Used regex: (?!(return)\b)\b\w+
\*(?!(m_p|p|s_p|m_ap|s_ap|g_p|g_ap|ap|gs_ap|ms_ap|gs_p|ms_p))\w+\b[^:\(p]

Fix CI fail
Fix misnamed non pointer as pointer and non array as array
Used regex: (?!(return|delete)\b)\b\w+ (m_|ms_|g_|gs_|s_)p\w+\b
(?!return\b)\b\w+ (ms_|m_|g_|gs_|s_)a\w+\b[^\[]

4687: Add Vulkan backend r=def- a=Jupeyy
This adds a Vulkan 1.0 backend and new features to the graphic settings to select the GPU(if multiple Vulkan GPUs are supported, and a new list for renderers (see screenshot below))
Mutleasy benchmark (CPU bound):
Vulkan multithreaded, single threaded vs OpenGL
(lower graphs are histograms, code by `@Chairn` )
Y = Frametimes in microseconds
lower graphs = amount of frametimes that happened (histogram)
(since the renderer speed differs, you should look at it more like a spread of values rather than the actual values)
![Figure_1](https://user-images.githubusercontent.com/6654924/153448356-941222a3-8bd3-424d-8685-a43389a4f691.png)
Vulkan is especially good in these scenarios, beating OpenGL 3.3 almost 3x with my setup (~600-700 FPS vs. ~1700-1800FPS)
Remaining TODO list:
- [x] compile shaders in cmake ( e.g. `https://gist.github.com/evilactually/a0d191701cb48f157b05be7f74d79396` )
- [ ] needs windows vulkan libraries
- [x] add build instructions (packages)
- [x] get away from coherent memory even for staging buffers (flushing memory just seems to be faster)
- [ ] a lot of testing :P

If there are bugs and it's crashing inside the driver the best you can do is to start the client with `dbg_gfx 4` which will (if supported) add Khronos standard validation layers + verbose debugging information + validation layer extensions, e.g. a synchronization validation layer and validation errors reported by the GPU driver directly.
(setting for dbg_gfx (0: none, 1: minimal, 2: affects performance, 3: verbose, 4: all))

Since it causes crashes because another thread just accesses the data.
No one has wanted to fix this, so maybe we should just remove it instead
of having clients crash in editor. I'm wondering how much effort it
would be to make this safe. Would we just have to lock for a short part
or is it basically the entire threaded undo operation that has to be
serialized? (No need for a thread then)
