Since C++17, non-member std::size() is present in the standard library
which also operates on regular C arrays. Given that, we can just replace
usages of ArraySize with that where applicable.
In many cases, we can just change the actual C array ArraySize() was
called on into a std::array and just use its .size() member function
instead.
In some other cases, we can collapse the loops they were used in, into a
ranged-for loop, eliminating the need for en explicit bounds query.
These vertex formats enable all attributes. Inactive attributes are set
to offset=0, and the smallest type possible. This "optimization" stops
the NV compiler from generating variants of vertex shaders.
They were only called at once, so no need to seperate them.
This also removes the only dereference of the NativeVertexFormat in VideoCommon, so backends may just return nullptr.
Yet another story of games loading weird shit into registers.
For some reason, Burnout 2 would (in rare situations) load invalid
addresses into cp_state.array_bases. What would the real hardware
do in this situation? Who knows, Burnout 2 doesn't actually enable
the vertex array with the invalid address so nothing kinky happens.
But dolphin tries to optimise things and starts using the address
as soon as it is loaded into memory. This causes GetPointer (which is
now much more vocal) to throw an error.
The Fix: We don't call GetPointer until we are sure the vertex array
has been enabled.
Results are still not correct, but things are getting closer.
* Don't cull CULLALL primitives so early so they can be used as reference
planes.
* Convert CalculateZSlope to screenspace coordinates.
* Convert Pixelshader to screenspace coordinates (instead of worldspace
xy coordinates, which is totally wrong)
* Divide depth by 2^24 instead of clamping to 0.0-1.0 as was done
before.
Progress:
* Rouge Squadron 2/3 appear correct in game (videos in rs2 save file
selection are missing)
* Shadows draw 100% correctly in NHL 2003.
* Mario golf menu renders correctly.
* NFS: HP2, shadows sometimes render on top of car or below the road.
* Mario Tennis, courts and shadows render correctly, but at wrong depth
* Blood Omen 2, doesn't work.
They are used to remove the flush amounts, but as we don't
flush anymore on vertex loader changes (only on native
vertex format right now), this optimization is now unneeded.
This will allow us to hard code the frac factors within the
vertex loaders.
