Change Details

On Windows the thumbnails of the files are cached in an internal file called `Thumbs.db`. Blender does not read the thumbs from this file, instead (for supported files with images, videos and .blend files), it loads, generates a thumb and saves he image in a cache located in: `C:\Users\%user%\.thumbnails\large` This is inefficient as it forces the loading of the files and causing a huge slowness at times. In addition to taking up HD space. --- This patch uses the Win 32 API to obtain an address that points to a bitmap in `Thumbs.db` generated for the file. Thus, it is no longer necessary to load the file. Ref T87621 --- **Unresolved problems:** - `SHCreateItemFromParsingName` and `IShellItemImageFactory::GetImage` do not work well in multithreaded (frequent crashes)
