Release: GL Tools, v1.5

Changes since GLTools 1.4

• New Stereo Environment patch, which renders its child patches twice using an asymmetric projection frustum, once for the right eye, once for the left eye, and provides each as an image output.
• New Look At patch (a two-point camera).
• New Camera patch (a one-point camera).
• Added "Image Structure" input to the GL Quad Structure patch.
• Fixed GL Inverse Rotation so that it executes every frame (rather than only once).
• Fixed SuperGLSLGrid so that color uniform values are properly set in 64bit mode.
• Separated the Alpha blendmode override to a separate plugin, so that GLTools itself doesn't perform any runtime hackery (and is thus somewhat less risky).
