AndroidEmulatorOGLBug.java

package com.demo;
//
// Demonstrates what appears to be a bug in smooth line drawing on the Android Emulator.
//
// This code works on a G1 and also JOGL on Windows, 
// but the line widths vary depending on endpoint location on the emulator.

// This code will work on the emulator if line smoothing is turned off.

// See http://gist.github.com/523961 for the other class (the renderer)
