<para>
|
|
<function>glPushAttrib</function> takes one argument,
|
|
a mask that indicates which groups of state variables
|
|
to save on the attribute stack.
|
|
Symbolic constants are used to set bits in the mask.
|
|
<parameter>mask</parameter>
|
|
is typically constructed by specifying the bitwise-or of several
|
|
of these constants together.
|
|
The special mask
|
|
<constant>GL_ALL_ATTRIB_BITS</constant>
|
|
can be used to save all stackable states.
|
|
</para>
|
|
<para>
|
|
The symbolic mask constants and their associated GL state are as follows
|
|
(the second column lists which attributes are saved):
