 This semi-small program has originally been written for my seminar paper and is released under the terms of the GNU General Public License v3.
 
 In the program itself you can just press the information button (the one with an i) to acess a simple explanation of this program. It is however not currently finished. While most of the essential features are implemented, some other, big features like an editor are planned (and a button reserved) but not implemented yet.

+## How to compile

+If you are on linux and have gcc installed you can just use the provided shell script to compile this example, otherwise you can compile it like this (again, clang should work too):

+
+```
+gcc -O3 -o resize *.c ../../lib/libSLK.a -lm -lSDL2 -lGL  -Wall #Compile to executable
+chmod +x ./resize #Only needed on unix(-like) systems

+# Performance
+
+This example messures the performance of the rgb and palettized software renderer included in  SoftLK. You can press r (rgb) and p(pal) to acess the two renderes and/or reset the timer. 
+
+On the top left you can see to numbers. The number on the left displays the average render time since the last reset, the right number shows how many sprites are beeing drawn. You can add more sprites by pressing/holding the space bar. In the top right corner the currently used renderer is beeing displayed.

 This example demonstrates dynamic sized windows, layer scaling, moving and resizing. The image is drawn on a seperate layer, the window itself is resizeable with layer 1 being resized dynamicly. Hold the ctrl key and scroll  the mouse wheel to scale the layer, hold the mouse wheel and move the mouse to move it.
