The solution is (using the original OpenGLScreenCapture project code) to modify this statement in FrameReader.m:

glCopyTexSubImage2D(GL_TEXTURE_RECTANGLE_ARB, 0, 0, 0, 0, 0, mWidth, mHeight);

to

glCopyTexSubImage2D(GL_TEXTURE_RECTANGLE_ARB, 0, 0, 0, 100, 50, mWidth+100, mHeight+50);

where I've obviously used constants, and mWidth and mHeight are the respective sizes of the desired snapshot.

I know it works - the product I used it in just shipped :-)
