Stephan Aßmus 954a0a0c33 Fix some cases of updating draw state while recording a BPicture
* Also implemented recording DrawString(string, length,
   BPoint[] locations), which was previously not recorded at all.
 * Also implemented playing back recently added drawing commands
   in PicturePlayer.cpp. I don't quite understand what this is
   actually used for, but it seemed it was forgotten. I just followed
   the pattern already established in the code.
 * The other important bit in this change is to update the pen
   location when it is needed while recording a BPicture. Often
   the BView will use PenLocation() in order to transmit drawing
   commands to the app_server which use absolute coordinates only.
   This isn't actually so nice, since it means the client has to
   wait for the server to transmit the current pen location. If there
   were dedicated link-commands for pen-relative drawing commands,
   the client could just keep sending without waiting for the server.
   In any case, the app_server needs to update the pen location in
   the current DrawState and even the DrawingEngine even while
   recording a picture, because some next command may need up-2-date
   state information, such as the font state and the pen location.
 * I have not yet tried to find /all/ instances where the DrawState
   needs to be updated while recording. This change should repair
   /all/ font state changes, all versions of drawing a string, and
   all versions of StrokeLine().
