Allow for a more modular renderer backends (#990)
* 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. https://en.cppreference.com/w/cpp/language/alignas * Fix Clang: alignas specifier Alignment must be specified before the array to align the entire array. https://en.cppreference.com/w/cpp/language/alignas * 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.

// Notes on the interpolator:
|
||||
//
|
||||
// This is a theory on how the DS hardware interpolates values. It matches hardware output
|
||||
// in the tests I did, but the hardware may be doing it differently. You never know.
|
||||
//
|
||||
// Assuming you want to perspective-correctly interpolate a variable named A across two points
|
||||
// in a typical rasterizer, you would calculate A/W and 1/W at each point, interpolate linearly,
|
||||
// then divide A/W by 1/W to recover the correct A value.
|
||||
//
|
||||
// The DS GPU approximates interpolation by calculating a perspective-correct interpolation
|
||||
// between 0 and 1, then using the result as a factor to linearly interpolate the actual
|
||||
// vertex attributes. The factor has 9 bits of precision when interpolating along Y and
|
||||
// 8 bits along X.
|
||||
//
|
||||
// There's a special path for when the two W values are equal: it directly does linear
|
||||
// interpolation, avoiding precision loss from the aforementioned approximation.
|
||||
// Which is desirable when using the GPU to draw 2D graphics.
