// Disables use of the OpenGL extension GL_ARB_texture_rectangle by JOGL's Texture creation utility.
//
// Between version 1.1.1 and version 2.x, JOGL modified its texture creation utility to favor
// GL_ARB_texture_rectangle over GL_ARB_texture_non_power_of_two on Mac OS X machines with ATI graphics cards. See
// the following URL for details on the texture rectangle extension: http://www.opengl.org/registry/specs/ARB/texture_rectangle.txt
//
// There are two problems with favoring texture rectangle for non power of two textures:
// 1) As of November 2012, we cannot find any evidence that the GL_ARB_texture_non_power_of_two extension is
// problematic on Mac OS X machines with ATI graphics cards. The texture rectangle extension is more limiting
// than the NPOT extension, and therefore not preferred.
// 2) World Wind assumes that a texture's target is always GL_TEXTURE_2D, and therefore incorrectly displays
// textures with the target GL_TEXTURE_RECTANGLE.
TextureIO.setTexRectEnabled(false);
// this.drawable.setGL(new DebugGL(this.drawable.getGL())); // uncomment to use the debug drawable
