Migrate Composite symbologies to use renmatrix by default

[terryburton]

Symbologies:

• gs1-128composite
• ean13composite
• ean8composite
• upcacomposite
• upcecomposite
• databaromnicomposite
• databarstackedcomposite
• databarstackedomnicomposite
• databartruncatedcomposite
• databarlimitedcomposite
• databarexpandedcomposite
• databarexpandedstackedcomposite

For each Composite symbology:

• Add correct border{left,right,top,bottom} support.

For EAN/UPC:

• Add text support.
• Add whitespace guard support. Depends on Add missing features from renlinear to renmatrix #261
• Verify add on positioning.
• Ensure border{left,right,top,bottom} is adjusted when add on is present.

usematrix option becomes redundant.

As a result, all encoders will invoke an single renderer unless dontdraw is specified, in which case only a single intermediate data structure will be left on the stack for an external renderer to process.
