/**
 * A WebGL Batcher for rendering textured triangle meshes.
 * Uses indexed drawing to efficiently render arbitrary triangle geometry.
 *
 * Owns mesh-mode GL state ownership (since 19.7 / #1468):
 *
 * - {@link MeshBatcher#bind} enters mesh mode — enables `DEPTH_TEST` +
 *   `LEQUAL` + `depthMask`, disables `BLEND`.
 * - {@link MeshBatcher#updatePassState} runs the one-shot
 *   `clearDepth(1.0) + clear(DEPTH_BUFFER_BIT)` when the active target's
 *   depth attachment is still dirty, immediately before a draw rather than
 *   on entry — `bind()` fires on a batcher *transition*, not once a frame,
 *   so a scene made only of meshes would otherwise never clear again after
 *   its first frame. Subsequent draws against the same target rely on the
 *   accumulated depth buffer.
 * - {@link MeshBatcher#unbind} exits mesh mode — restores non-mesh
 *   defaults (`BLEND` on, `DEPTH_TEST` off, `depthMask` false) that the
 *   2D rendering paths assume.
 * - Subscribes to {@link event.RENDER_TARGET_CHANGED} (emitted by the
 *   renderer at frame-start `clear()`, non-camera FBO bind, post-effect
 *   FBO unbind) to re-arm the lazy depth clear whenever the active
 *   framebuffer's attachments change identity.
 *
 * The WebGLRenderer doesn't know any of this — `setBatcher("mesh")` calls
 * `bind()` and the batcher sets up its own pass, refreshing whatever is
 * per-draw as it goes. Same lifecycle ports
 * cleanly to a future WebGPU renderer: `bind()` becomes "begin a
 * depth-enabled `RenderPassEncoder`", `unbind()` ends it.
