+/**
+ * Used to track whether we are within a series of simple primitive operations
+ * or texturing operations. The op parameter determines the nature of the
+ * operation that is to follow. Valid values for this op parameter are:
+ *
+ * GL_QUADS
+ * GL_LINES
+ * GL_LINE_LOOP
+ * GL_LINE_STRIP
+ * (basically any of the valid parameters for glBegin())
+ *
+ * GL_TEXTURE_2D
+ * GL_TEXTURE_RECTANGLE_ARB
+ *
+ * OGL_STATE_RESET
+ * OGL_STATE_CHANGE
+ * OGL_STATE_MASK_OP
+ * OGL_STATE_GLYPH_OP
+ *
+ * Note that the above constants are guaranteed to be unique values. The
+ * last few are defined to be negative values to differentiate them from
+ * the core GL* constants, which are defined to be non-negative.
+ *
+ * For simple primitives, this method allows us to batch similar primitives
+ * within the same glBegin()/glEnd() pair. For example, if we have 100
+ * consecutive FILL_RECT operations, we only have to call glBegin(GL_QUADS)
+ * for the first op, and then subsequent operations will consist only of
+ * glVertex*() calls, which helps improve performance. The glEnd() call
+ * only needs to be issued before an operation that cannot happen within a
+ * glBegin()/glEnd() pair (e.g. updating the clip), or one that requires a
+ * different primitive mode (e.g. GL_LINES).
+ *
+ * For operations that involve texturing, this method helps us to avoid
+ * calling glEnable(GL_TEXTURE_2D) and glDisable(GL_TEXTURE_2D) around each
+ * operation. For example, if we have an alternating series of ISO_BLIT
+ * and MASK_BLIT operations (both of which involve texturing), we need
+ * only to call glEnable(GL_TEXTURE_2D) before the first ISO_BLIT operation.
+ * The glDisable(GL_TEXTURE_2D) call only needs to be issued before an
+ * operation that cannot (or should not) happen while texturing is enabled
+ * (e.g. a context change, or a simple primitive operation like GL_QUADS).
