Since most encoders/decoders (invoked by Spice) may not work properly with tiled memory associated with a texture, we need to create another texture that has linear memory layout and use that instead. Note that, there does not seem to be a direct way to indicate to the GL implementation that a texture's backing memory needs to be linear. Instead, we have to do it in a roundabout way where we need to first create a tiled texture and import that as a memory object to create a new texture that has a linear memory layout.
