+--[[TEXT WIDGET v1.. by Wlourf 25/06/2010
+This widget can drawn texts set in the "text_settings" table with some parameters
+http://u-scripts.blogspot.com/2010/06/text-widget.html
+
+The parameters (all optionals) are :
+text - text to display, default = "Conky is good for you"
+ use conky_parse to display conky value ie text=conly_parse("${cpu cpu1}")
+ - coordinates below are relative to top left corner of the conky window
+x - x coordinate of first letter (bottom-left), default = center of conky window
+y - y coordinate of first letter (bottom-left), default = center of conky window
+h_align - horizontal alignement of text relative to point (x,y), default="l"
+ available values are "l": left, "c" : center, "r" : right
+v_align - vertical alignment of text relative to point (x,y), default="b"
+ available values "t" : top, "m" : middle, "b" : bottom
+font_name - name of font to use, default = Free Sans
+font_size - size of font to use, default = 14
+italic - display text in italic (true/false), default=false
+oblique - display text in oblique (true/false), default=false (I don' see the difference with italic!)
+bold - display text in bold (true/false), default=false
+angle - rotation of text in degrees, default = 0 (horizontal)
+colour - table of colours for text, default = plain white {{1,0xFFFFFF,1}}
+ this table contains one or more tables with format {P,C,A}
+ P=position of gradient (0 = beginning of text, 1= end of text)
+ 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 of the text
+ for a gradient with three colours {{0,0x00FF00,0.5},{0.5,0x000033,1},{1,0x440033,1}}
+ and so on ...
+orientation - in case of gradient, "orientation" defines the starting point of the gradient, default="ww"
+ there are 8 available starting points : "nw","nn","ne","ee","se","ss","sw","ww"
+ (n for north, w for west ...)
+ theses 8 points are the 4 corners + the 4 middles of text's outline
+ so a gradient "nn" will go from "nn" to "ss" (top to bottom, parallele to text)
+ a gradient "nw" will go from "nw" to "se" (left-top corner to right-bottom corner)
+radial - define a radial gradient (if present at the same time as "orientation", "orientation" will have no effect)
+ this parameter is a table with 6 numbers : {xa,ya,ra,xb,yb,rb}
+ they define two circle for the gradient :
+ xa, ya, xb and yb are relative to x and y values above
+reflection_alpha - add a reflection effect (values from 0 to 1) default = 0 = no reflection
+ other values = starting opacity
+reflection_scale - scale of the reflection (default = 1 = height of text)
+reflection_length - length of reflection, define where the opacity will be set to zero
+ calues from 0 to 1, default =1
+skew_x,skew_y - skew text around x or y axis
+
+
+Needs conky 1.8.0
+
+To call this script in the conkyrc, in before-TEXT section:
+ lua_load /path/to/the/lua/script/text.lua
+ lua_draw_hook_pre draw_text
+
+v1.0 07/06/2010, Original release
+v1.1 10/06/2010 Add "orientation" parameter
+v1.2 15/06/2010 Add "h_align", "v_align" and "radial" parameters
+v1.3 25/06/2010 Add "reflection_alpha", "reflection_length", "reflection_scale",
+ "skew_x" et "skew_y"
