This plugin requires ImageMagick to be installed. The exact ImageMagick version required seems to be around 6.3.9-6. I am using 6.3.7 without problems but 6.2 has been reported not to work. Thanks to Dario C. for this information!
QuickEffects can perform many of the tasks you typically needed to open your graphic editor to use.
In your facelift directory, edit plugins/QuickEffects.php and change define('IM_EXEC_PATH', ''); to the location of your ImageMagick binaries (with a trailing slash).
Create a new FLIRStyle Object and set the mode to 'quickeffects'. You could do this by passing it along with the FLIR.init call:
FLIR.init( new FLIRStyle( { mode:'quickeffects' } ) );

Option qe_Stroke: 'Stroke_Width int pixels, Stroke_Color Hex Color (no #)'
new FLIRStyle( { mode:'quickeffects'
, qe_Stroke: '2,006400' } )
Option qe_Fill: 'pattern, relative/path/to/fill_image.jpg'
It is recommended to create a facelift sub-directory to store your fill images in.
Working directory is the facelift root.
new FLIRStyle( { mode:'quickeffects'
, qe_Fill: 'gradient,qe-pattern-fill-texture.jpg' } )

Option qe_Fill: 'gradient, top_color Hex Color without # symbol, bottom_color Hex Color without # symbol'
new FLIRStyle( { mode:'quickeffects', qe_Fill: 'gradient,add8e6,0000ff' } )

Option qe_Shadow: 'high or low or fuzzy' ...or...
Option qe_Shadow: 'opacity int (1-100), sigma int (0-4 is pretty good), offset left int (negatives allowed), offset top int (negatives allowed)'
new FLIRStyle( { mode:'quickeffects', qe_Shadow: 'low' } )

new FLIRStyle( { mode:'quickeffects'
, qe_Stroke: '2,000000'
, qe_Fill: 'gradient,add8e6,0000ff'
, qe_Shadow: 'low' } )
