made quad inherit from ofNode
first try ad edge blending
test
begins to work, but textures are white and shade effect is not warped with quad
segfaults on i915
starting to work on nvidia, still crashes when mouse is released and quads transparency is not working
transparency fixed
starts to works, now must find a way of making the shader stuff right
tweaked edge-blend shader
seems to work basically, now it is a performance issue
removed version number from frag shader
added controls for edge blending. changed color scheme
added feature to displace content in quads
added several blending modes to quad class. would be nicer with a shader, but not working well on older GPUs, so stuck with gl_blend option
moved homography code to a new header file
updated codeblocks file
tweaked quad resize code, adding window resize event. made testApp inherit from ofBaseApp instead than ofSimpleApp
added little triangle in active quad draggable corner when warping with mouse, added an isActive property to quads
