 * Whether a texture can go through the perspective mesh.

 * Only textures owning their whole source qualify. An atlas SUB-frame does
 * not: the mesh addresses its source with plain 0..1 UVs, and remapping them
 * onto the frame - via `texture.uvs`, via `textureMatrix`, or leaving it to
 * PixiJS - has not produced a correct draw here. Unmapped, the cell shows the
 * whole sheet; mapped by hand, a magnified crop of the right frame, which says
 * the mapping is applied somewhere else too. Rather than ship either, a
 * sub-frame falls back to the affine fit in `ReelSymbol.applyCellQuad()` -
 * correct, just not keystoned.
 *
 * Generated textures, single loaded images and render textures pass. Atlas
 * frames - the common production case - do not, yet.
