+--[[BOX WIDGET v1.0 by Wlourf 19/12/2010
+This widget can drawn some boxes, even circles in your conky window
+http://u-scripts.blogspot.com/ (HowTo coming soon)
+
+Inspired by Background by londonali1010 (2009)
+
+The parameters (all optionals) are :
+x - x coordinate of top-left corner of the box, default = 0 = (top-left corner of conky window)
+y - y coordinate of top-left corner of the box, default = 0 = (top-left corner of conky window)
+w - width of the box, default = width of the conky window
+h - height of the box, default = width of the conky window
+radius - radius of the corner, default = 0 = no radius
+mode - mode for drawing the radius, possible values are "circle" or "curve", default ="curve"
+linear_gradient - table with the coordinates of two points to define a linear gradient,
+ points are relative to top-left corner of the box, (not the conky window)
+ {x1,y1,x2,y2}
+radial_gradient - table with the coordinates of two circle to define a radial gradient,
+ colour={{0,0xCCCCCC,1},{1,0xCCCCCC,0}} points are relative to top-left corner of the box, (not the conky window)
+ {x1,y1,r1,x2,y2,r2} (r=radius)
+colour - table of colours, default = plain white {{1,0xFFFFFF,1}}
+ this table contains one or more tables with format {P,C,A}
+ P=position of gradient (0 = start of the gradient, 1= end of the gradient)
+ C=hexadecimal colour
+ A=alpha (opacity) of color (0=invisible,1=opacity 100%)
+ Examples :
+ for a plain color {{1,0x00FF00,0.5}}
+ for a gradient with two colours {{0,0x00FF00,0.5},{1,0x000033,1}}
+ or {{0.5,0x00FF00,1},{1,0x000033,1}} -with this one, gradient will start in the middle
+ for a gradient with three colours {{0,0x00FF00,0.5},{0.5,0x000033,1},{1,0x440033,1}}
+ and so on ...
+
+
+
+To call this script in Conky, use (assuming you have saved this script to ~/scripts/):
+ lua_load ~/scripts/draw_bg.lua
+ lua_draw_hook_pre main_box
+
+And leave one line blank or not after TEXT
