Attributes<br />
• Attributes are flags and values that are part of the graphics state,<br />
and are therefore associated with individual primitives.<br />
• The values of these attributes are pushed and popped with the<br />
graphics state.<br />
• This is done with the AttributeBegin and AttributeEnd<br />
commands<br />
• The attribute block is the fundamental block for encapsulating<br />
user entities.<br />
