[x3d-public] add memory management functionality to X3D 4?

Memory management to support adaptive LODs for high/medium/low resolution has always been a bit of a challenge in X3D.

Often authors end up optimizing to support all platforms, especially low-memory systems - which drives down quality on commodity systems..

Wondering if there is some property we might add in the Browser API under Scene Authoring Interface (SAI) to give authors/libraries access so that they can boost quality through better use of memory management.

Purging memory cache (or purging outside of current frustum, etc.) might be another function of interest.  Or perhaps inputOnly purge/reload fields on ImageTexture/MovieTexture nodes?

Doubtless the APIs for individual X3D players have their own mechanisms for this functionality, might be some generalizable ideas there.

Please post if you have had problems or solutions with this problem.  Thanks for considering the possibilities.

all the best, Don
