/* PRACTICAL EXPLANATION:

The TPassiveCacheManager's purpose is that of storing render results from a specified set of fx nodes.

When an fx is passed to the manager to be cached, a structure of type FxData is generated for the fx.

It is stored inside the manager and ASSOCIATED to the fx through an INDEX key - this one being stored

inside the fx data.

In particular, the FxData instances contain a PERSISTANT identifier (passiveCacheId) that is saved inside

the scene data, a flag specifying the cache status of the fx node (like, if it's enabled or not), and

a description of the schematic dag below the associated fx.

Now, when a resource request is made to the TPassiveCacheManager, it checks the FxData about the generating

fx - if it contains the flag specifying that it must be cached, a resource is allocated (if not already

present), a reference to it is stored, and finally the resource is returned.

References to interesting resources are stored in a TABLE container, indexed by "rendering context" and

fx. A rendering context is hereby intended as a SEQUENCE of render processes where the next render of the

sequence is assumed to REPLACE the previous one.

We therefore have one context for the swatch viewer, one for File>Preview, one for the Preview Fx of each

fx node, and one context for EACH FRAME of the sceneviewer preview (one frame is not supposed to replace

another in that case).

The table is in practice a map of maps (a kind of 'comb' structure) - where the primary map is associated

by render context and the secondary ones by fx. This mean that we are able to address and iterate contexts

easier than fxs. Values of the table are set of resources.

RESOURCES MAINTENANCE POLICY:

As resources use a concrete amount of memory for storage, they should be kept in the resources table only

for the time they are supposedly useful to the user. There are 2 ways of dealing with this issue.

1) First, we can track scene changes and eliminate those resources that will no longer be accessed due to the

applied change. This happens, for example, when a level is being drawn, fxs are inserted, moved or removed.

Level changes are delivered immediately to the ::invalidateLevel(..) method, which removes all resources

whose name contains the level's name. Unfortunately, this cannot be done at frame precision (ie you cannot

invalidate a single frame of the level, but ALL the level).

Xsheet (schematic) changes are tracked through the schematic node description stored inside the FxData structure.

Once one such change happens, all resources update their description - if that changes, the associated resources

are released.

The same schematic description is used to track and release resources affected by changes on a downstream fx's

parameters.

There are also scene changes that are inherently hard to track or intercept. For example, pegbar affines changes,

fx nodes expressions referencing data not directly connected to the fx, and possibly others. These are currently

NOT handled by direct tracking.

2) As there may be resources which escape the resource control by point (1), we need some extra control

policies. Here they are:

We assume that the pool of resources accessed by render processes of a same render context should be CONSTANT

IF NO SCENE CHANGE HAPPENS. In other words, we are guessing that only those resources used in the last

rendering will be used in the next. Resources accessed in a render but NOT in the next (of the same context)

are released.

However, it could be that the sequence of render processes from a context is halted from a certain moment on.

In that case, it is a waste to keep the resources accessed by its last render if no new render will ever take

place. We then assume further that a rendering context can be ENABLED or DISABLED - when a render context is

enabled, it will most likely have a next render - and therefore can keep its resources in memory.

Once a context is DISABLED, it moves the resources to a TEMPORARY context.

Resources in the temporary context are those 'on their way for release'. They will be KEPT only if the

next rendering - INDEPENDENTLY FROM THE RENDER CONTEXT - requires them (in this case, they will be adopted

by the new context). This is necessary since context disables typically happen when a preview window closes.

It is not unfrequent that users close the preview window, modify the scene, and then restore the preview.

CONSIDERATIONS:

* The File>Render generates NO CONTEXT - and therefore does NOT PASSIVELY CACHE RESOURCES, since it cannot be

  stated whether it is in the 'enabled' or 'disabled' state. It could be considered coherent with what tcomposer

  does, by the way...

* Our resources maintenance policy ensures that the memory usage should be stable over time - that is, no

  useless resource is kept in memory.

  Of course, it is possibly more restrictive than what the user may desire. For example, closing 2 preview

  windows marks their resources for deletion, but only one of the two restored previews will keep its

  resources intact...
