why: - the current splash-screen has no referring to official images on - https://en.bitcoin.it/wiki/Promotional_graphics - the current splash screen only exists in a low res jpg - current splash screen looks dark and "hackish" - new splash screen should generate positive, "trust-emotions". - new splash screen gives the user infos about the running client. - new splash screen can handle long messages (in a lot of - languages the text is cropped in current release) - new size (x2) 400x312 - contains textual information about the client - textinfos are dynamicly written to the pixmap when -testnet is switch on, the splashscreen will show the bitcoin logo in testnet-color (as well as a text [testnet]) example: https://dl.dropbox.com/u/7383846/new_bitcoin_splash.png
