* Instead of just configuring SPIR-V disassemblers and picking only the first
one when we need to edit SPIR-V, we allow setting up any shader processor that
goes between two shader encodings.
* When editing, the default will still be to use embedded source, and then after
that the first tool that goes from the native shader format to a text format,
but the drop-down allows you to pick any of them.
* Similarly in the shader viewer you can configure the compilation options and
method, to choose the compiler you want to use. Embedded command line
parameters in the shader are automatically appended.
* The main addition here apart from some extra stubs is a new rdc type
for date time objects.
* Although the module doesn't do anything and is only used for docs
reflection it is desirable to not have to link against Qt as this
can cause problems when linking the module without unresolved symbols.
* The former is only needed inside tp_init of a new object. Instead when
we want to pass in and own a pointer, we use SWIG_POINTER_OWN.
* This also removes the need to pass 'self' all the way down in
ConvertToPy which tidies up a lot of code.
