plotframe - plot a frame with scaling and grids
: vector [wantgrids,findbounds] where wantgrids is a boolean variable (%t or %f) which indicates gridding. findbounds is a boolean variable. If findbounds is %t, the bounds given in rect are allowed to be slightly modified (in fact always increased) in order to have simpler graduations: then tics(2) and tics(4) are ignored.
plotframe is used with 2D plotting functions plot2d, plot2d1,... to set a graphics frame. It must be used before plot2d which should be invoked with the "000" superposition mode.
