/**
* 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).
