\brief Data class containing the relevant additional informations needed in
a render process.
\details This class stores most of the data required by Toonz and single fxs
to
perform a render. While a good part of this data group is used
internally
by Toonz to deal with global aspects of a rendering process, another
part
must be actively referenced when rendering an fx.
The most important member of this class is \p m_affine, which
specifies
the affine transform that must be applied by an fx if it were to
render
on the default reference.
\sa TRasterFx::compute() for further informations.

/*!
A standard Toonz Fx is roughly composed of 2 parts: one providing the
necessary
interface for access by a GUI interface (covered by the TFx class, which this
class
inherits), the other for the actual computation of the fx - which is the focus
of the TRasterFx interface.
\n\n
So, the essential part of this class lies in the compute() and doCompute()
methods that
are invoked to perform an fx computation. The former method is the publicly
accessed one, while
the latter is the one that fx writers must reimplement to supply their
rendering code.
\n
The allocateAndCompute() method can be used to automatically allocate the tile
to be rendered
right before invoking compute().
\n\n
The dryCompute() / doDryCompute() methods are required by Toonz to perform
predictive caching
in order to minimize needless recomputations of the same fx. Fx writers must
reimplement
doDryCompute() to mimic the behaviour of doCompute() in terms of compute()
invocations for children
fx nodes. Those compute() invocations must be replaced with dryCompute().
\n\n
The getBBox() / doGetBBox() methods are used to obtain the geometry of the
maximal output that an
fx can produce with similar inputs to compute(). Again, doCompute() is the
method to reimplement
by subclasses. Observe that, unlike doCompute() and doDryCompute(), in this
case the affine supplied
with the render settings must be \b ignored (see the method itself for further
details).
\n\n
The canHandle() / handledAffine() methods are used by the compute() function
to separate the part of
an affine that the doCompute() can apply to the result on its own from the
rest (which is automatically
applied on the fx result using TRasterFx::applyAffine() ).
Note that every Toonz fx should be able to handle at least the scale part of
an affine (applying
TRasterFx::applyAffine() on image enlargements typically hampers image
quality).
\n\n
Further methods whose reimplementation depends on the fx itself are
getAlias(), which must return
a string uniquely descripting a rendered object, and getMemoryRequirement() to
declare the amount of
memory that will be used by the fx.
