support of typed array for records/arrays

[vadim.godunko]

Data structures for WebGL should preserve raw memory structure to be able to be send to GL server. This requires support from A2JS. For example:

   type Point is record
      X : OpenGL.GLfloat;
      Y : OpenGL.GLfloat;
      Z : OpenGL.GLfloat;
      A : OpenGL.GLubyte;
      B : OpenGL.GLubyte;
      C : OpenGL.GLubyte;
   end record;

   type Point_Array is array (Positive range <>) of Point;

or

   type Point is record
      Coords : OpenGL.GLfloat_Vector_3;
      Id     : OpenGL.GLubyte_Vector_3;
   end record;

   type Point_Array is array (Positive range <>) of Point;

Set of possible types of members are limited:

• Interfaces.Integer_8 (and derived)
• Interfaces.Unsigned_8 (and derived)
• Interfaces.Integer_16 (and derived)
• Interfaces.Unsigned_16 (and derived)
• Interfaces.Integer_32 (and derived)
• Interfaces.IEEE_Float_32 (and derived)
• vectors and matrices of above types (note, matrices should have convention Fortran to be mapped properly)

In 5618:

Revert [5599]. Refs #453

Represent TypedArray record as Object instead of TypedArray.
So we can return to original type representation.

In 5619:

Create type in a subprogram as 'var TypeName='

[Maxim Reznik]

In 5620:

Add _cast function to convert record aggregate

to corresponding record type. This applies prototype to record
aggregates. Refs #453
