NAME
       glScissorIndexed - define the scissor box for a specific viewport


C SPECIFICATION
       void glScissorIndexed(GLuint index, GLint left, GLint bottom, GLsizei width, GLsizei height);

       void glScissorIndexedv(GLuint index, const GLint *v);


PARAMETERS
       index
           Specifies the index of the viewport whose scissor box to modify.

       left, bottom
           Specify the coordinate of the bottom left corner of the scissor box, in pixels.

       width, height
           Specify ths dimensions of the scissor box, in pixels.

       v
           For glScissorIndexedv, specifies the address of an array containing the left, bottom, width and
           height of each scissor box, in that order.


DESCRIPTION
       glScissorIndexed defines the scissor box for a specified viewport.  index specifies the index of scissor
       box to modify.  index must be less than the value of GL_MAX_VIEWPORTS. For glScissorIndexed, left,
       bottom, width and height specify the left, bottom, width and height of the scissor box, in pixels,
       respectively. For glScissorIndexedv, v specifies the address of an array containing integers specifying
       the lower left corner of the scissor box, and the width and height of the scissor box, in that order.

       To enable and disable the scissor test, call glEnable() and

       glDisable with argument GL_SCISSOR_TEST. The test is initially disabled for all viewports. While the test
       is enabled, only pixels that lie within the scissor box can be modified by drawing commands. Window
       coordinates have integer values at the shared corners of frame buffer pixels.  glScissor(0,0,1,1) allows
       modification of only the lower left pixel in the window, and glScissor(0,0,0,0) doesn't allow
       modification of any pixels in the window.

       When the scissor test is disabled, it is as though the scissor box includes the entire window.


ERRORS
       GL_INVALID_VALUE is generated if index is greater than or equal to the value of GL_MAX_VIEWPORTS.

       GL_INVALID_VALUE is generated if any width or height specified in the array v is negative.


ASSOCIATED GETS
       glGet() with argument GL_SCISSOR_BOX

       glIsEnabled() with argument GL_SCISSOR_TEST
