//RSX matrices passed already map to the [0, 1] range but mapping to classic OGL requires that we undo this step
//This can be made unnecessary using the call glClipControl(GL_LOWER_LEFT, GL_ZERO_TO_ONE).
//However, ClipControl only made it to opengl core in ver 4.5 though, so this is a workaround.
//NOTE: It is completely valid for games to use very large w values, causing the post-multiplied z to be in the hundreds
//It is therefore critical that this step is done post-transform and the result re-scaled by w
//SEE Naruto: UNS
//NOTE: On GPUs, poor fp32 precision means dividing z by w, then multiplying by w again gives slightly incorrect results
//This equation is simplified algebraically to an addition and subreaction which gives more accurate results (Fixes flickering skybox in Dark Souls 2)
//OS << " float ndc_z = gl_Position.z / gl_Position.w;\n";
