Creating a bump map from any image

REDsdk implements bump mapping through the support of normal maps. To convert any bump map to a normal map, simply do:

RED::Object* image2d;

RC_TEST( RED::ImageTools::Load( image2d, "./my_bump_map.hdr", RED::FMT_RGB, false, false, RED::TGT_TEX_2D, iresmgr->GetState() ) );

RED::IImage2D* i2d = image2d->As< RED::IImage2D >();
RC_TEST( i2d->NormalMap( RED::FMT_RGB, RED::TGT_TEX_2D, 3.f, image2d, iresmgr->GetState() ) );
