736 * Used to track whether we are within a series of simple primitive operations
737 * or texturing operations. The op parameter determines the nature of the
738 * operation that is to follow. Valid values for this op parameter are:
739 *
740 * GL_QUADS
741 * GL_LINES
742 * GL_LINE_LOOP
743 * GL_LINE_STRIP
744 * (basically any of the valid parameters for glBegin())
745 *
746 * GL_TEXTURE_2D
747 * GL_TEXTURE_RECTANGLE_ARB
748 *
749 * OGL_STATE_RESET
750 * OGL_STATE_CHANGE
751 * OGL_STATE_MASK_OP
752 * OGL_STATE_GLYPH_OP
753 *
754 * Note that the above constants are guaranteed to be unique values. The
755 * last few are defined to be negative values to differentiate them from
756 * the core GL* constants, which are defined to be non-negative.
757 *
758 * For simple primitives, this method allows us to batch similar primitives
759 * within the same glBegin()/glEnd() pair. For example, if we have 100
760 * consecutive FILL_RECT operations, we only have to call glBegin(GL_QUADS)
761 * for the first op, and then subsequent operations will consist only of
762 * glVertex*() calls, which helps improve performance. The glEnd() call
763 * only needs to be issued before an operation that cannot happen within a
764 * glBegin()/glEnd() pair (e.g. updating the clip), or one that requires a
765 * different primitive mode (e.g. GL_LINES).
766 *
767 * For operations that involve texturing, this method helps us to avoid
768 * calling glEnable(GL_TEXTURE_2D) and glDisable(GL_TEXTURE_2D) around each
769 * operation. For example, if we have an alternating series of ISO_BLIT
770 * and MASK_BLIT operations (both of which involve texturing), we need
771 * only to call glEnable(GL_TEXTURE_2D) before the first ISO_BLIT operation.
772 * The glDisable(GL_TEXTURE_2D) call only needs to be issued before an
773 * operation that cannot (or should not) happen while texturing is enabled
774 * (e.g. a context change, or a simple primitive operation like GL_QUADS).
