[AD] [PATCH] al_convert_bitmap in bitmap.c

[Dennis-Busch@xxxxxxxxxx]

(patch is attached)

Patch notes:
fixed al_convert_bitmap for case (from pure memory to video bitmap)

As it was, it was causing a problem with ex_loading_thread when using the
default Direct3D driver on conversion of previously loaded memory bitmaps.

Problem description before the fix:
The bitmaps loaded in line 30 in ex_loading_thread
  30  bitmaps[load_count] = al_load_bitmap("data/mysha.pcx");
were never uploaded to texture memory.

This caused the later call in line 166 in ex_loading_thread
 166  al_convert_bitmap(bitmaps[loaded_bitmap]);
to copy the wrong pixel data (from the empty texture of the created
clone instead of from the memory buffer of the source bitmap)
resulting in empty textures and empty memory buffers in the converted
bitmap so the bitmaps never showed up on screen.
