[GDI32] -Implement GdiDrawStream.
- This is based on the prototype I found in a sample app on codeproject. I don't really know what the unknown parameters are for but I haven't found anything yet passing different values. Almost all of the code is from the drawing code from uxtheme with the only difference that in uxtheme UXTHEME_DrawImageBackground reads several values from the theme but his takes them as parameters. I don't see any reason to spend time understanding what these are for. I found what the draw flags are for by passing different values in the test application and trying to replicate the parameters that UXTHEME_DrawImageBackground need. I decided to keep the naming like that since it is almost verbatim wine code. At some point it should be moved to win32k however. CORE-4420 svn path=/trunk/; revision=74280
