* Draft GPU3D renderer modularization
* Update sources C++ standard to C++17
The top-level `CMakeLists.txt` is already using the C++17 standard.
* Move GLCompositor into class type
Some other misc fixes to push towards better modularity
* Make renderer-implementation types move-only
These types are going to be holding onto handles
of GPU-side resources and shouldn't ever be copied around.
* Fix OSX: Remove 'register' storage class specifier
`register` has been removed in C++17...
But this keyword hasn't done anything in years anyways.
OSX builds consider this "warning" an error and it
stops the whole build.
* Add RestartFrame to Renderer3D interface
* Move Accelerated property to Renderer3D interface
There are points in the code base where we do:
`renderer != 0` to know if we are feeding
an openGL renderer. Rather than that we can instead just have this be
a property of the renderer itself.
With this pattern a renderer can just say how it wants its data to come
in rather than have everyone know that they're talking to an OpenGL
renderer.
* Remove Accelerated flag from GPU
* Move 2D_Soft interface in separate header
Also make the current 2D engine an "owned" unique_ptr.
* Update alignment attribute to standard alignas
Uses standardized `alignas` rather than compiler-specific
attributes.

* Fix Clang: alignas specifier
Alignment must be specified before the array to align the entire array.

* Converted Renderer3D Accelerated to variable
This flag is checked a lot during scanline rasterization. So rather
than having an expensive vtable-lookup call during mainline rendering
code, it is now a public constant bool type that is written to only once
during Renderer3D initialization.

VRAM dirty tracking
* clip against Z then Y then X. apparently, fixes#310. I had also observed hints that the hardware does it this way.
* truncate W to 24 bits before viewport transform.
* mark any polygons that have a W=0 at that point as degenerate. do not render.
this, by a fucking shitshow of butterfly effect, ends up fixing #234. technically, the rasterizer was going out of bounds, which, under certain circumstances, caused interpolation to shit itself and generate Z values that were out of range (but still ended up in the zbuffer). sometimes those values ended up negative, which caused these glitches when polygons had to be drawn over those.
about fucking time.
rendering translucent pixels preserves opaque polygonID and edge flags for edgemarking.
fixes edgemarking malfunctions, like #80 or black dots in Pokémon games
* undo 'winding sorting' hypothesis
* special depth test rules: 'less than' function becomes 'less or equal' when rendering front-facing polygon pixels against back-facing opaque pixels
