On the revamp-webgl branch, I have a first-pass implementation of multichannel rendering within WebGL`. That branch currently supporst up to 8 channels as 8 textures, rendered together per tile 1) when tiles load 2) when settings change. The "tile-loaded" event from Openseadragon indicates that cached image tiles are often discarded when they exit the viewport.
