Fix for screenshot crash at 1366 x 768 resolution (Intel Graphics)

Got a shiny new laptop. Native screen resolution is 1366 x 768. But sadly, I discovered that TGE corrupts memory data whenever I take a screenshot at this resolution.

The fix seems to be as simple as adding a call to glPixelStorei(GL_PACK_ALIGNMENT,1) in the console function "screenShot":

ConsoleFunction(screenShot, void, 3, 3, "(string file, string format)"
                "Take a screenshot.\n\n"
                "@param format One of JPEG or PNG.")
{
   FileStream fStream;
   if(!fStream.open(argv[1], FileStream::Write))
   {   
      Con::printf("Failed to open file '%s'.", argv[1]);
      return;
   }
   
   glReadBuffer(GL_FRONT);
   glPixelStorei(GL_PACK_ALIGNMENT,1);  // <<---- Here's the call to fix the crash @ 1366 x 768

   // ...rest of function unchanged...
}

Adding that call to glPixelStorei() prevents glReadPixels() from overwriting memory. Apparently, the default value of GL_PACK_ALIGNMENT is 4 (or at least it is for my laptop's Intel HD Graphics OpenGL driver). The added call simply sets it to 1.

Hope that helps somebody else. I'm surprised I didn't find any existing forum posts about this issue.
