GLPOLYGONSTIPPLE()                                          GLPOLYGONSTIPPLE()

NAME
       glPolygonStipple - set the polygon stippling pattern

C SPECIFICATION
       void glPolygonStipple( const GLubyte *mask )

PARAMETERS
       mask  Specifies a pointer to a 32 x 32 stipple pattern that will be
             unpacked from memory in the same way that glDrawPixels unpacks
             pixels.

DESCRIPTION
       Polygon stippling, like line stippling (see glLineStipple), masks out
       certain fragments produced by rasterization, creating a pattern.
       Stippling is independent of polygon antialiasing.

       mask is a pointer to a 32 x 32 stipple pattern that is stored in memory
       just like the pixel data supplied to a glDrawPixels call with height
       and width both equal to 32, a pixel format of GL_COLOR_INDEX, and data
       type of GL_BITMAP.  That is, the stipple pattern is represented as a 32
       x 32 array of 1-bit color indices packed in unsigned bytes.
       glPixelStore parameters like GL_UNPACK_SWAP_BYTES and
       GL_UNPACK_LSB_FIRST affect the assembling of the bits into a stipple
       pattern.  Pixel transfer operations (shift, offset, pixel map) are not
       applied to the stipple image, however.

       To enable and disable polygon stippling, call glEnable and glDisable
       with argument GL_POLYGON_STIPPLE. Polygon stippling is initially
       disabled. If it's enabled, a rasterized polygon fragment with window
       coordinates x_w and y_w is sent to the next stage of the GL if and only
       if the (x_w mod 32)th bit in the (y_w mod 32)th row of the stipple
       pattern is 1 (one).  When polygon stippling is disabled, it is as if
       the stipple pattern consists of all 1's.

ERRORS
       GL_INVALID_OPERATION is generated if glPolygonStipple is executed
       between the execution of glBegin and the corresponding execution of
       glEnd.
