/**
* The parser identifies VTK types with 32-bit hexidecimal numbers:
*
* - One byte is for the base type.
* - One byte is indirection i.e. & and * and "* const"
* - One byte is for qualifiers like const and static.
* - The final byte is reserved.
*
* There is some type information that cannot be stored within
* this bitfield. This info falls into three categories:
*
* 1) Function pointers are stored in a FunctionInfo struct.
* However, if the type is VTK_PARSE_FUNCTION with no POINTER,
* it is guaranteed to be "void func(void *)" which is the
* old VTK-style callback.
*
* 2) Multi-dimensional arrays are stored in a char *[MAX_ARRAY_DIMS]
* array with a NULL pointer indicating there are no more brackets.
* If the type is a pointer and the first value is not NULL, then
* that value gives the array size for that pointer. The reason
* that "char *" is used is because the sizes might be template
* parameters or constants defined elsewhere. However, most often
* the sizes are integer literals, and the first size will be
* stored as an int in ArgCounts.
*
* 3) The ID for VTK_PARSE_OBJECT is stored in ArgClasses.

/**
* Indirection, contained in VTK_PARSE_INDIRECT
*
* Indirection of types works as follows:
* type **(**&val[n])[m]
* Pointers on the left, arrays on the right,
* and optionally a set of parentheses and a ref.
*
* The 'type' may be preceded or followed by const,
* which is handled by the VTK_PARSE_CONST flag.
*
* The array dimensionality and sizes is stored
* elsewhere, it isn't stored in the bitfield.
*
* The leftmost [] is converted to a pointer, unless
* it is outside the parenthesis.
* So "type val[n][m]" becomes "type (*val)[m]",
* these two types are identical in C and C++.
*
* Any pointer can be followed by const, and any pointer
* can be preceded by a parenthesis. However, you will
* never see a parenthesis anywhere except for just before
* the leftmost pointer.
*
* These are good: "(*val)[n]", "**(*val)[n]", "(*&val)[n]"
* Not so good: "(**val)[n]" (is actually like (*val)[][n])
*
* The Ref needs 1 bit total, and each pointer needs 2 bits:
*
* 0 = nothing
* 1 = '*' = VTK_PARSE_POINTER
* 2 = '[]' = VTK_PARSE_ARRAY
* 3 = '* const' = VTK_PARSE_CONST_POINTER
*
* The VTK_PARSE_ARRAY flag means "this pointer is actually
* the first bracket in a multi-dimensional array" with the array
* info stored separately.
