A suggestion related to enhancing compatibility

[Ricepies]

in view.cpp ~300th line
maybe replace with the following code

    const int zsize = zl*zl;
    // GLfloat zs[zsize];
    std::vector<GLfloat> zs(zsize);

#ifndef HAVE_GLES
    glReadBuffer(GL_FRONT);
    // glReadPixels(x-radius,y-radius,zl,zl,GL_DEPTH_COMPONENT,GL_FLOAT,zs);
    glReadPixels(x - radius, y - radius, zl, zl, GL_DEPTH_COMPONENT, GL_FLOAT, zs.data());
#else
    std::fill(zs,zs+zsize, 0.8);
#endif

    //const GLfloat mindepth = *(std::min_element(zs,zs+zsize));
    const GLfloat mindepth = *std::min_element(zs.begin(), zs.end());
    return mindepth;
}

Do you have an example of such an issue and how to reproduce this on the CI runner?

Can you send a PR for the fix? We can then check this in the CI.
