+Peach skin by Dakal, Marianne Gagnon, and CrystalDaEevee, released under creative-commons BY-SA 3.0+
+Except background.jpg, by elisee
+Except stars, by s@f
+
+To make your own skin, I suggest simply duplicating this file and modifying it as needed.
+There are two types of images : some will be simply stretched as a whole, others will
+have non-stretchable borders (you cannot choose which one you must use, it's hardcoded
+for each element type; though, as you will see below, for all "advanced stretching" images
+you can easily fake "simple stretch")
+
+All elements will have at least 2 properties :
+        type="X"                                sets what you're skinning with this entry
+        image="skinDirectory/imageName.png"     sets which image is used for this element
+
+Most elements also support states :
+        state="neutral"
+        state="focused"
+        state="down"
+You can thus give different looks for different states.  Not all widgets support all states,
+see entries and comments below to know what's supported.
+Note that checkboxes are an exception and have the following styles :
+    "neutral+unchecked"
+    "neutral+checked"
+    "focused+unchecked"
+    "focused+checked"
+    "deactivated+unchecked"
+    "deactivated+checked"
+
+"Advanced stretching" images are split this way :
+
+     +----+--------------------+----+
+     |    |                    |    |
+     +----+--------------------+----+
+     |    |                    |    |
+     |    |                    |    |     
+     |    |                    |    |     
+     +----+--------------------+----+
+     |    |                    |    | 
+     +----+--------------------+----+
+     
+The center border will be stretched in all directions. The 4 corners will not stretch at all.
+Horizontal borders will stretch horizontally, verticallt borders will stretch vertically.
+Use properties left_border="X" right_border="X" top_border="X" bottom_border="X" to specify
+the size of each border in pixels (setting all borders to '0' makes the whole image scaled).
+
+In some cases, you may not want vertical stretching to occur (like if the left and right sides
+of the image must not be stretched vertically, e.g. for the spinner). In this case, pass
+parameter preserve_h_aspect_ratios="true" to make the left and right areas stretch by keeping
+their aspect ratio.
+
+Some components may fill the full inner area with stuff; others will only take a smaller
+area at the center. To adjust for this, there are properties "hborder_out_portion" and "vborder_out_portion"
+that take a float from 0 to 1, representing the percentage of each border that goes out of the widget's
+area (this might include stuff like shadows, etc.). The 'h' one is for horizontal borders,
+the 'v' one is for vertical borders.
+
+Finnally : the image is split, as shown above, into 9 areas. In osme cases, you may not want
+all areas to be rendered. Then you can pass parameter areas="body+left+right+top+bottom"
+and explicitely specify which parts you want to see. The 4 corner areas are only visible
+when the border that intersect at this corner are enabled.
+
+When there is a common="y" with image tag, the image will be loaded only from data/skins/common in stk-code.

+Here you can configure advanced theming rules for this skin
+Currently STK supports:
+1. Icon theme
+2. Font
+
+To allow icon theme, use the tag icon_theme="y" and then place the replacement png into
+(local skin folder)/data/gui/icons, STK will prefer those first, if not found it will fallback to bundled icon.
+
+For TTF specify the list like the following, for normal and digit ttf it will be added in the beginning of font
+list in STK, so those TTF will be used first, and any missing character will be rendered from the bundled font
+list. For color emoji ttf it will be replace the bundled color emoji directly. You are not required to specify
+all types of ttf.
