Quick THEME howto for SLiM

Some basic information regarding the slim theme format.
Read this file if you plan to make some theme for
the program, and of course have a look at the included themes

GENERAL CONCEPT
    A SLiM theme essentially consists of:
    - a background image (background.png or background.jpg)
    - a panel image (panel.png or panel.jpg)
    - input box(es) and messages and their placement
      and properties (slim.theme)
    
    The panel and background images can be a PNG or JPEG file.
    The panel is blended into the background image,
    taking care of alpha transparency.

SUPPORTED FORMATS
    - fonts: use the xft font specs, ie: Verdana:size=16:bold
    - colors: use html hex format, ie #0066CC
    - positions: can be either absolute in pixels, ie 350
      or relative to the container, ie 50% is in the middle
      of the screen.

SHADOWS

    The 'msg', 'input', 'welcome', 'session' and 'username' sections
    support shadows; three values can be configured:
    - color: the shadow color
    - x offset: the offset in x direction, relative to the normal text 
    - y offset: the offset in y direction, relative to the normal text

    So to add a text shadow to the welcome message, add the following
    to slim.conf:
    ----------------------------------------------------------------------
    welcome_shadow_xoffset      -2
    welcome_shadow_yoffset      2
    welcome_shadow_color        #ff0000
    ----------------------------------------------------------------------
     
    The other keys are analogue:
    ----------------------------------------------------------------------
    # for username and password label
    username_shadow_xoffset 	2
    username_shadow_yoffset 	-2
    username_shadow_color   	#ff0000

    # for the input fields
    input_shadow_xoffset 	1
    input_shadow_yoffset 	1
    input_shadow_color   	#0000ff

    # for the messages:
    msg_shadow_xoffset 		1    
    msg_shadow_yoffset 		1    
    msg_shadow_color   		#ff00ff

    # For the session:
    session_shadow_xoffset 		1    
    session_shadow_yoffset 		1    
    session_shadow_color   		#ff00ff
