Memory Management

[mhusinsky]

VL.Espace lacks proper memory management for image handling, which results in Gen2 garbage collections (i.e. stutters in the rendering).

Issues stem from continuous memory allocation with every image decompression that are not properly handled.

as a hacky workaround to the framedrops, with there is now also a Spout proxy that is meant to be run in its own instance. it receives images and makes them available as spout textures, that can be consumed in another (the "main") patch.
