//! Raw GL-to-wgpu import primitives with no surfman dependency.
//!
//! These functions accept raw GL handles (FBO IDs, IOSurface pointers, etc.)
//! and produce `wgpu::Texture` objects. They can be used by any GL producer,
//! not just surfman-based ones.
/// BGRA-to-RGBA and Y-flip normalization pass for imported textures.
