Opengl charts do not fill the available space

[lesquoyb]

Describe the bug Contrary to java2D charts, opengl ones do not fill the whole available space, leading to clumsy displays

To Reproduce Copy paste this model:

/**
* Name: fill
* Based on the internal empty template. 
* Author: baptiste
* Tags:

model fill

global
{
    list<float> myldata <- [];
    list<list<float>> mylldata <- [[]];
    list<list<float>> mylldata2 <- [[]];
    int xsize <- 100;
    int ysize <- 100;
    init
    {
        do update_chart();
    }

    reflex do_action
    {
        do update_chart();
    }

    action update_chart
    {
        myldata <- [];
        mylldata <- [];
        loop xi from: 0 to: xsize - 1
        {
            add cos((xi + cycle * 20) * 2) to: myldata;
            add [] to: mylldata;
            loop yi from: 0 to: ysize - 1
            {
                add cos((xi + cycle * 10)) + cos((yi + cycle * 10)) to: mylldata[xi];
            }

        }

        mylldata2 <- [];
        loop xi from: 0 to: xsize - 1
        {
            add [] to: mylldata2;
            loop yi from: 0 to: ysize - 1
            {
                add sin((xi + cycle * 10)) + sin((yi)) to: mylldata2[xi];
            }

        }

    }

}

experiment "Different heatmaps" type: gui
{
    output synchronized: true
    {
        display "3D" type: 3d axes:false
        {
            chart "3D" type: xy {               
                data "test" value: mylldata color: [# darkblue, # orange] accumulate_values: false;
            }
        }
        display "2D" type: 2d axes:false
        {
            chart "2D" type: xy {               
                data "test" value: mylldata color: [# darkblue, # orange] accumulate_values: false;
            }
        }

    }
}

Observe the rendering difference between 2d and 3d, while both display the same data

Expected behavior Both 2d and 3d charts fill the whole space available to them

A warning is now emitted when a 3d display is used to display only charts. I think we will not go further on this !
