This will allow us to replace the GLSL FFP pipes, and is useful for testing the FFP HLSL backend before the Vulkan backend is mature enough in other respects.
This patch introduces the d3d setting "ffp_hlsl", set to a DWORD value. It is disabled by default, and only has an effect on the GL renderer. --- dlls/wined3d/adapter_gl.c | 1 + dlls/wined3d/cs.c | 8 ++++ dlls/wined3d/glsl_shader.c | 72 +++++++++++++++++++++++++--------- dlls/wined3d/wined3d_main.c | 5 +++ dlls/wined3d/wined3d_private.h | 5 ++- 5 files changed, 70 insertions(+), 21 deletions(-)
