This function will take a screenshot.
- This function does same thing as pressing the PrtScn button on your keyboard. It will capture a screen image and write it to a file.
- Save a file with the following format: "WoWScrnShot_MMDDYY_HHMMSS.tga".
- "...\World of Warcraft\Screenshots".
- The format can be controlled by the "screenshotFormat" Config.wtf variable which was introduced in Patch 1.11. It can be set to "tga" (default), "jpeg" or "png".
