RenderColorMesh memory leak hint?

If you are still maintaining this code, I hope this will be of some help:

The memory leak in RenderColorMesh may be coming from improper release of the OffScreenGL created in the function.

A temporary workaround can be achieved by replacing the lines:

===================
OffscreenGL offscreenGL((int)(imgSizeV[0] * zoomFactor), (int) (imgSizeV[1] * zoomFactor));
int output3Size[3];

unsigned char *imgBuffer;

if (offscreenGL.RGB8Setup()) {

mexPrintf("OpenGLCanvas setup Successful\n");

with the lines

static OffscreenGL offscreenGL((int)(imgSizeV[0] * zoomFactor), (int) (imgSizeV[1] * zoomFactor));
static bool not_first_entry = false;
int output3Size[3];

unsigned char *imgBuffer;

if (not_first_entry || offscreenGL.RGB8Setup()) {
if(!not_first_entry){
mexPrintf("OpenGLCanvas setup Successful\n");
}

not_first_entry=true;

this stems the leak, though it does not fix it (X11 continues to run in the background and eventually crash if called unexpectedly)
