Fix the sky in one of the levels in virtua on. The problem was caused by the fact we didn't split the mesh by the fog % burn through, so all the polys had the same value. We could use a vertex attrib, but % burn through fog is so rarely used and when it is, normally every poly in the mesh has the same value.

- New JTAG emulation, moved into its own class, CJTAG
- Removed game-specific sun clamp hacks from CNew3D (JTAG and Real3D emulation will call the appropriate method to configure this at run-time)
- Removed JTAG from Real3D save state data and reused some of that space for new state variables having to do with the internal JTAG-based config as well as new frame timing state variables

Calculating the length of the vertex results in quite broken values for fogging when the vertices are traversing the view frustum. The hardware also wouldn't have been doing a square root per vertex for fogging. Simply using the z values is enough. Todo check clamping of values for the near/far planes.

Modern hardware does backface culling in window space by calculating the face normal for the polygon, then doing a dot product against the view vector. The real3d pro-1000 on the other hand passes a pre-calculated face normal for each polygon which is used for culling. We were using this face normal to rewind the polygons so that regular backface culling would work. This worked 99.9% of the time. However this was failing on some models in Virtua Striker. The reason was because the pre-calculated face normals being passed were actually completely different to the actual face normals for the poly (not just inverted like you would expect). This broke our code. The solution was to emulate face culling directly in the vertex shader using the pre-calculated face normals directly. Only minimally tested this but hopefully there are no obvious regressions.

Harry made some important discoveries with regards to fixed shading on the model 3 (per vertex poly brightness values). Firstly values are allowed to be negative, and they are used as a drop in replacement in the standard lighting equation for the normal dot light vector. This quite radically changes the brightness in LA Machine guns, but now correctly matches the arcade.

Finish fixed shading for 2.0 hardware. I'm pretty sure it actually works identically to step 1.5 hardware. The oddball is LA machine guns where the viewport ambient doesn't seem to effect the brightness. But the ambient works differently in this game because it uses the unclamped light model. Still need to investigate if the diffuse factor effects fixed shading.

Sometime ago I managed to work out that specular on the model3 is not real specular, and really is just an extension of diffuse lighting. But attempts were derailed by corner cases and the fact we were not handling the normals correctly. Anyway Harry managed to successfully come up with an algorithm, and coefficients that give an almost perfect match to specular on the model3, based soley on observations from video footage! He also worked out that the lighting on hardware 1.5 onwards appears to be unclamped (ie greater than 1). This quite radically changes the brightness of some of the games, but much better matches the original hardware.

Ski champ for some reason is passing denormalised numbers for the modelscale. This is causing a NaN in our shader killing the lighting for these models, so we simply skip these, since they are essentially zero anyway. Thanks to Harry for finding this bug :)

We were force normalising the result of matrix * normal, which looked correct in most cases. But this didn't preserve the scaling of the matrix, or the scaling of the model normals which resulted in many over bright areas. On it's own this generally worked, but games like Star Wars looked quite broken. Harry correctly figured out if you scale these normals by the scaling value that is sometimes present in the culling nodes the lighting looks correct. Still more work to do to correctly figure out the model3's lighting model.

Clamp the ambient light to a max of 0.75. LA Machine guns seems to use an ambient value of 1, which is full bright for everything. But for some reason the hardware seems to treat this as ~ 0.75. This fixes various missing shading in the game. This doesn't seem to have any negative effects on other games I have tested. Clamping in the shader as we might need the full range of values for fixed shading.

A second go at fixing the fixed lighting in star wars .. Fixed shading is per vertex poly colours. For some reason in star wars they are treated as unsigned values instead of signed, like in every other game. These polys are all marked with specular enabled, where as in the rest of the games they are missing this flag. That's the only difference I can find.

The real3d has a flag that allows the hw to skip polygons so that they aren't rendered. Sega rally2 uses this for the dust effects. Triangles or quads that have this flag are junk, and look like random corruption if you try to draw them. We assumed polys that shared vertices with these bad polygons were also bad. It turns out the last few shared vertices in these polys were in fact valid, and thus the entire quad/triangle strip should be drawn and not discarded.

Originally to do mipmapping, I just used the base texture and then let the h/w automatically generate the mipmap chain. I wasn't sure the real3d api even exposed to the programmer the ability to directly set the mipmap data. Anyway, as pointed out by HarryTuttle scud actually uses darker mipmaps for an effect on the water. This patch uses the uses the actual mipmap data from the real3d memory. Only tested scud, so hopefully I didn't cause any cataclysmic errors :)

The model3 has this weird issue where the 2d and 3d planes are misaligned by 2 pixels. Originally I made a quick hack that shifted subviewports 2 pixels. But apparently that wasn't enough, as the issue effects everything. Thanks to HarryTuttle for pointing this out, and making a patch :)

The hardware actually seems to treat the quad primitive as a triangle strip. The winding order can actually change between the first and second 'triangle' inside the quad, leading our code to incorrectly backface cull the 2nd triangle. So we must re-calculate the winding order for the 2nd triangle. This fixes a massive missing poly in the road in la machine guns, probably other games too. The hardware is unaffected by the winding order, as it doesn't calculate the poly normal from the vertices directly, instead it uses the provided normal in the poly header.

Support microtexture relative scale. The exact scaling values are not known, but a 2x difference between each level seems highly likely. We know from visual inspection from scud that the first level is exactly 4. The SDK has a function that accepts a float input for scale and does this. lod = (1/scale) + 0.5. If lod>3 lod = 3. So this is our best guess.

The model3 shares vertices between polygons. But it also seems to do this for polygons with different textures. This means the texture coordinate for potentially different sizes textures is shared. Currently this was broken leading to some corrupted looking textures. The fix is to simply cache the old texture coordinates, and recalculate the normalised coordinates in the new texture coordinate space.
