[Piglit] [PATCH 08/18] arb_geometry_shader4: Test valid drawing modes.

Test that glDrawArrays() triggers the required errors.

The geometry shader input type limits the valid primitive types of glBegin()
(including implicit glBegin()).

>From the ARB_geometry_shader4 spec (section Errors):
"The error INVALID_OPERATION is generated if Begin, or any command that
implicitly calls Begin, is called when a geometry shader is active and:

    * the input primitive type of the current geometry shader is
      POINTS and <mode> is not POINTS,

    * the input primitive type of the current geometry shader is
      LINES and <mode> is not LINES, LINE_STRIP, or LINE_LOOP,

    * the input primitive type of the current geometry shader is
      TRIANGLES and <mode> is not TRIANGLES, TRIANGLE_STRIP or
      TRIANGLE_FAN,

    * the input primitive type of the current geometry shader is
      LINES_ADJACENCY_ARB and <mode> is not LINES_ADJACENCY_ARB or
      LINE_STRIP_ADJACENCY_ARB, or

    * the input primitive type of the current geometry shader is
      TRIANGLES_ADJACENCY_ARB and <mode> is not
      TRIANGLES_ADJACENCY_ARB or TRIANGLE_STRIP_ADJACENCY_ARB."
