getscreensizeinpixelspc

function screenSize = getscreensizeinpixelspc
%GETSCREENSIZEINPIXELSPC  Same as get(0, 'ScreenSize'), but dynamic.
%		SZ = GETSCREENSIZEINPIXELSPC returns a 1x4 vector of doubles giving the
%		size of the display in pixels, in the same way as get(0, 'ScreenSize'),
%		except it reads the current settings rather than reading a static copy
%		made at MATLAB startup time.
%
%		GETSCREENSIZEINPIXELSPC uses a Win32 API call and therefore will only
%		work on Windows. Type "mex getscreensizeinpixelspc.c" to compile the
%		mex-file. If the mex-file is not found, the normal static screen size
%		retrieval is used.

%
%		Note: The corresponding mex-file was taken from the Matlab Central
%		contribution "Get screen size (dynamic)" from Russell Goyder.
