       void glUniformMatrix4fvARB( GLuint location,

       transpose Specifies  if the matrix should be transposed as it is loaded

       value	 Specifies pointer to array containing values used  to	update

DESCRIPTION
       glUniformARB  sets the values for a uniform variable or a uniform array
       for the program object which is currently in use (part  of  the	OpenGL
       rendering  state).   A  Uniforms is referenced using its location which
       can be queried by  calling  glGetUniformLocationARB.   When  a  program
       object  is  successfully	 linked	 all,  locations are generated for all
       active uniforms belonging to the program object and the uniform	values
       are  initialized to zero.  These locations are invalidated and new ones
       assigned after each successful re-link.

       Uniform variables and arrays are	 named	and  declared  in  a  shader's
       source  code.   Values for these uniforms remain constant over a primi‐
       tive. Uniforms are program object specific state.   They	 retain	 their
       values  once  loaded,  and their values are restored whenever a program
       object is used, as long as the program object has not been re-linked. A
       uniform	is considered "active" if it is determined by the compiler and
       linker that the uniform will actually be accessed when  the  executable
       code  is executed. In cases where the compiler and linker cannot make a
       conclusive determination, the uniform will be considered active.

NOTES
       Uniform variables which are defined as samplers can only be modified by
       calling glUniform1iARB and glUniform1ivARB.

ERRORS
       GL_INVALID_OPERATION  is	 generated  if	there  is  no  current program
       object.

       GL_INVALID_OPERATION is generated if the size of the  uniform  variable
       in  the	shader	does  not match the size indicated in the glUniformARB
       command.

       GL_INVALID_OPERATION is generated if a sampler is loaded using  a  com‐
       mand other than glUniform1iARB or glUniform1ivARB.

       GL_INVALID_OPERATION  is generated if the type of the variable declared
       in the shader does not match that the type of the function used to load
       the uniform variable.

       GL_INVALID_OPERATION  is	 generated  if	number of values used load the
       variable is greater than the number of values declared in the shader.

       GL_INVALID_OPERATION is generated if location is not a  valid  location
       for the current program object.

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

ASSOCIATED GETS
       glGetUniformARB with the handle of a program object.

       glGetUniformLocationARB with the handle of a  program  object  and  the
       name of a uniform variable.

       glGetUniform  the handle of a program object and the location of a uni‐
       form variable.
