fix(shaders): a surface marked as metal in specgloss but with an albedo darker than any real metal is lit as the painted or dirty dielectric it stands for, with its diffuse back and its highlight held to 0.06, instead of going black without a diffuse term, and a metal reflects its surroundings at least at half strength whatever the alpha of its normal map says, since its reflection is all of its colour; materials without specgloss stay as they were

fix(shaders): the highlight of the sun is multiplied by the cosine of its light, so surfaces no longer glare milky white under a low sun; headlights light a surface with 1.35 of its diffuse colour and add a GGX highlight of their own scaled by specgloss and param_specular instead of multiplying the whole light by one plus param_specular; normalmap, parallax, detail, shadowless, sunless and default_detail materials read param_glossiness as a Phong exponent, roughness = (2 / (n + 2))^1/4, instead of 1 - 1/n or a fixed mirror

feat(render): ambient occlusion with bent normals darkens only the light of the surroundings instead of the whole image, so the sun and headlights keep their full strength; the occlusion and the bent normal of the previous frame are reprojected into the lighting of the scene, with the motion of the camera and of every vehicle and cab taken into account and with depth checks against disocclusion, the ambient light follows how much of the sky the bent normal sees, and reflections of the environment are occluded where the cone of visible directions around the bent normal cuts off the reflected lobe, only where the occlusion is clear enough that open flat panels and windows keep their grazing reflections

feat(render): ground truth ambient occlusion darkens creases, recesses and the space under desks and frames, computed at half resolution from the reversed depth buffer with a depth-aware blur and multiplied into the image before motion blur, so it works with the default settings; thin parts in front of a surface, such as a steering wheel, shade it only from close by, and gfx.postfx.gtao.enabled, radius, intensity, directions and steps set it from the ini

fix(render): dark parts of a cab and of the running gear are no longer crushed to black, as the AgX look raises its contrast power from 1.0 in the shadows up to 1.6 only from the middle tones on, which keeps the bright tones, the outside view and the night as they were but leaves black knobs, levers and lettering visible on a black desk; the light of a cab can be scaled with gfx.cab.ambient, 1.0 by default

fix(shaders): parallax mapping reads its depth from a mip about four texels per pixel coarser, filtered bicubically where the hit is refined, so the relief no longer breaks into stalactites and the edges of stones no longer step along the texel grid of the compressed depth; it takes 16 to 64 layers by the angle of view and six steps of refinement, casts the shadows of the relief from the sun over the sun light and darkens the hollows deeper than the mean depth of the texture while lightening the tops, so the mean brightness of a surface stays the same

fix(shaders): parallax mapping of the opengl33 materials is shared by the four parallax shaders in parallax.glsl and samples its depth with the gradients of the surface instead of letting a loop of varying length pick the mip level, picks the number of layers by the angle of view alone and refines the hit with a binary search instead of one linear step, so stones near the camera no longer show combs of layer slices; it fades out between 60 and 100 m instead of stopping at a hard line and fades out at grazing angles, and the simple offset without extra effects no longer divides by an unbounded cosine of the view

tonemapping: Fix up AgX application
...
We're supposed to output linear values there, as sRGB transfer function
gets applied either by GL framebuffer or FBOUT later on.
min_ev and max_ev also need to be adjusted, as they're tweaked for
a pipeline with exposure compensation. The current values lead to a very
washed-out image, which was "hidden" by subsequently applying gamma twice.
It may make sense to revisit these values in the future to better match
the rendering pipeline.
