TGEA 1.8.0 - DDS textures without mips assert Torque.

DDS textures without mip maps make you run into an assert.
Which of course is nonsense. Removing the assert call doesn't seem to break anything, but I haven't made any tests yet as we're still porting. Our Waterblocks rely on a DDS texture for depth effects and oil patches, and there's no reason to keep such a texture mipmapped AFAIK.
bool GFXD3DxTextureManager::_loadTexture(GFXTextureObject *aTexture, DDSFile *dds)
{

if( !dds->mFlags.test( DDSFile::MipMapsFlag ) )
{
// Great, we have to generate our own mips.
String fileName("<Unknown>");
// Try to find a useful name
if (dds->getSourcePath().getFullFileName().isNotEmpty())
fileName = dds->getSourcePath().getFullFileName().c_str();
else if (aTexture->mTextureLookupName.isNotEmpty())
fileName = aTexture->mTextureLookupName.c_str();
#ifdef TORQUE_DEBUG
else if (aTexture->mDebugDescription.isNotEmpty())
fileName = aTexture->mDebugDescription.c_str();
#endif
AssertISV(false, avar("DDS texture %s doesn't have mipmaps. You need to generate them as part of your .dds.", fileName.c_str()));

OMG I hated seeing this error in the early development of Lore Aftermath, of course back then it said something like " is lazy! Automatic MipMap Generation is not supported!"

In fact Torque should never autogenerate mipmaps for DDS files... if the artist didn't export a DDS with mipmaps you should assume thats what they wanted.
