resize_uninitialized()

template<typename T>

void blender::io::hydra::resize_uninitialized ( pxr::VtArray< T > & array, const int new_size )

static

#VtArray::resize() does value initialization of every new value, which ends up being memset for the trivial attribute types we deal with here. This is unnecessary since every item is initialized via copy from a Blender mesh here anyway. This specializes the resize call to skip initialization.
