// For reference, I'm starting a list of unhandled flags here. I'm sure I missed some,
// so feel free to add to this, or remove ones that are handled that I missed.
// Cases where these values are set would be useful, too.
//
// In GIFRegHandlerFOG, I don't see gs.vertexregs.f being used anywhere afterwards.
// GIFRegHandlerTEX1 doesn't look like anything other then mmag and mmin are handled.
// This includes:
// lcm - the lod (level of detail) calculation method. If 0, it's (log2(1/|Q|)<<L)+K), whereas if it is one, it's just K.
// mxl - This is what MIPMAP level we use. The default is 0, and any other level uses miptbp0 & 1 to get the texture width.
// mtba - this is the base address specification for MIPMAP level 1+.
// l - Yeah, this is for the LOD calculation.
// k - This too.
// This largely sums up as that we don't support MIPMAP level 1+ (much like GSdx), and LOD.
//
// In GIFRegHandlerSCANMSK, it doesn't look like gs.smask is used, though it may have been in the old resolve code.
// Lets see: 00 is normal drawing, 01 is reserved, 10 prohibits drawing to even y coords, and 11 prohibits drawing to odd y coords.
//
// In GIFRegHandlerMIPTBP1 & 2, both miptbp0 & miptbp1 look unused, which isn't suprising, given mxl not being checked.
//
// GIFRegHandlerDIMX doesn't even have any code in it!
// This is supposed to read in the matrix for dithering.
//
// In GIFRegHandlerDTHE, nothing is done with gs.dthe.
// This goes right with the last one, because dthe is set to 1 when dithering with the dthe matrix.
// In GIFRegHandlerCOLCLAMP, gs.colclamp is not used.
// This is color clamping on the RGB value. If it's 0, it is set to mask, the lower 8 bits are enabled, and it wraps around. At 1, it is clamped from 0-255.
