// Purpose:
//
//
// The dx8 implementation of the shader API
//===========================================================================//
/*
DX9 todo:
-make the transforms in the older shaders match the transforms in lightmappedgeneric
-fix polyoffset for hardware that doesn't support D3DRS_SLOPESCALEDEPTHBIAS and D3DRS_DEPTHBIAS
- code is there, I think matrix offset just needs tweaking
-fix forcehardwaresync - implement texture locking for hardware that doesn't support async query
-get the format for GetAdapterModeCount and EnumAdapterModes from somewhere (shaderapidx8.cpp, GetModeCount, GetModeInfo)
-record frame sync objects (allocframesyncobjects, free framesync objects, ForceHardwareSync)
-Need to fix ENVMAPMASKSCALE, BUMPOFFSET in lightmappedgeneric*.cpp and vertexlitgeneric*.cpp
fix this:
// FIXME: This also depends on the vertex format and whether or not we are static lit in dx9
#ifndef SHADERAPIDX9
if (m_DynamicState.m_VertexShader != shader) // garymcthack
#endif // !SHADERAPIDX9
unrelated to dx9:
mat_fullbright 1 doesn't work properly on alpha materials in testroom_standards
