Base class for user defined transforms.
MPxTransform allows the creation of user defined transform nodes. User defined transform nodes can introduce new transform types or change the transformation order. They are designed to be an extension of the standard Maya transform node and include all of the normal transform attributes. Standard behaviors such as limit enforcement and attribute locking are managed by this class, but may be overriden in derived classes.
In general, a complete implementation of user defined transforms will require the deriving from two classes; MPxTransform defines the node while MPxTransformationMatrix describes the mathematical functions of the user defined transform.
The MPxTransform class is registered using the MFnPlugin::registerTransform() method. Both the MPxTransform and the MPxTransformationMatrix classes are registered in the same method. This allows for a clear association between a MPxTransform and a MPxTransformationMatrix. Both the MPxTransform and the MPxTransformationMatrix classes need unique MTypeIds.
MPxTransform nodes are DAG nodes and therefore a change to one element will affect every node beneath the changed node. Since this can involve quite a bit of calculation, DAG nodes internally handle clean and dirty differently than other nodes. What this means is that the updateMatrixAttrs() method should be used when getting one of the matrix attributes from a method on this node. Additionally, after a value is changed, the appropriate dirty method (i.e. dirtyTranslate(), dirtyRotate(), etc.) should be called. When in doubt, dirtyMatrix() will flag everything as needing to be updated.
It is up to each transform node to determine if it will obey limits or not. Since transform attributes may have limits or may be involved in some sort of constraint, there needs to be a way to accept, reject, or modify a value when a plug is set on the node. The mustCallValidateAndSet() method allows for this kind of control. When an attribute is flagged with the mustCallValidateAndSet() method in the initialize() method, every plug change will call the validateAndSetValue() method for approval. From the validateAndSetValue() method things like limits and value locking can be enforced. It is important to note that for new attributes on the transform node, any locking or limits are left as an implementation detail.
If any of the public methods are affected by the addition of transform components, or by the order of computation, they should be overriden in the derived class. Many of the public methods are used by internal Maya code and exist for more than just convenience.
The createTransformationMatrix() class must be overloaded if a transformation matrix other than the default MPxTransformationMatrix is used.
NOTES: 1) The setDependentsDirty() virtual method is available in this class since MPxTransform derives from MPxNode. During a call to MPxTransform::setDependentsDirty(), a plug-in should not invoke any of the dirty*() or updateMatrixAttrs() calls of this class. For example, the methods dirtyMatrix(), dirtyTranslation() or updateMatrixAttrs() should not be called. 2) Updating world space attributes is an expensive operation. Maya updates world space attributes on demand such as in the case of a getAttr being issued or a connection exists for the attribute.

Post constructor.
Internally maya creates two objects when a user defined node is created, the internal MObject and the user derived object. The association between the these two objects is not made until after the MPxNode constructor is called. This implies that no MPxNode member function can be called from the MPxNode constructor. The postConstructor will get called immediately after the constructor when it is safe to call any MPxNode member function.

This method returns the type of the node.
This method should not be overridden by the user. It will return MPxNode::kTransformNode.

If a derived MPxTransformationMatrix is used as the transformation matrix for the node, then this method must be overridden.

This method should be overridden to return true if the user supplies a bounding box routine.
Supplying a bounding box routine makes refresh and selection more efficient.

This method should be overridden to return a bounding box for the transform.
If this method is overridden, then MPxTransform::isBounded should also be overridden to return true.

Maya's base transform node type is treated differently from node types which are derived from it.
For example, the 'viewFit' command does not include transform nodes in its calculations but does include pointConstraint nodes which are derived from the transform node.
By default, all custom transform node types are treated the same as Maya's base transform node type. Using the same example, by default a custom transform node will be excluded from the 'viewFit' command's calculations.
This method allows that default behaviour to be changed. By overriding this method to return false, a custom node can turn off the special treatment accorded to transform nodes and instead have itself treated the same as Maya treats derived transform nodes.

The transform's compute method.
The compute method should call any supporting methods to proper handle limits as well as the cases where the plug's value should not change. The MPlug::isFreeToChange() method is used to determine if a plug's value may be changed.
When the compute method on derived classes is invoked for an attribute not handled by the derived class, the derived class should call MPxTransform::compute to allow the base classes to handle the attribute.

When a plug's value is set, and the plug is on a default transform attribute, or has been flagged by the mustCallValidateAndSet() method, then this method will be called.
The purpose of validateAndSetValue() is to enforce limits, constraints, or plug value locking.
If the plug passed into this method is not an attribute related to the derived class, the derived class should call the validateAndSetValue method of its parent class in order to allow the base classes to handle their attributes.
If any adjustments or corrections are required, they are placed in the data block and if the context is normal, into the cached transformation matrix. Values on the data block are in transform space.
Formerly the context was passed in; now the context will already be set as the current one for evaluation so it isn't necessary. To retrieve the current evaluation context, call MDGContext::current.
If you have specialty code that calls this method directly you'll have to ensure the current context is set using MDGContextGuard or MDGContext::makeCurrent.

This method is used only for the MPxTransform and MPxTransform derived classes.
It will ensure that the values which change the resulting 4x4 matrix are current. It should be called before getting values that affect the matrix calculation.

This method must be called in the initialize() method for all attributes that affect the matrix of the transform.
It will ensure that the matrix is properly calculated when the passed attribute is changed and that the validateAndSetValue method will get called for this attribute.
It is only for MPxTransform derived classes.
If a custom attribute on an MPxTransform derived classes is declared as "mustValidateAndSetValue", then the validateAndSetValue method must be implemented, so that it takes the data out of the data handle, and sets it into the datablock of the node.

Normal Maya transforms consist of translate, rotate, scale, and shear.
All of these transform types produce an affine matrix. With MPxTransform it is possible to introduce non-affine matrices into places that previously did not consider their effects.
If non-affine matrices are enabled, then all calculations which require additional operations when handling non-affine matrices will perform the addition mathematical operations.
This is a static method and will affect all transforms when enabled.

This method is used to modify and set the new translate values being passed in from the compute method or from the validateAndSetValue.
The data block should be set with the corrected values. Corrections would come from enforcing any active limits as well as verifying that the plug's value may be changed. If the plug is locked or if it is the destination in a connection that disallows value changes, then the plug will be set to its unchanged value.
