gimp: Update version from 2.10.0 to 2.10.2

Article [1] and change-log [2].

> Core:
>
>   - Discard fonts which fail to load and popup an info dialog to allow
>     people debug their fonts.
>   - New API to suppress updates in UI until plug-ins are done
>     introducing changes.
>   - New API to calculate histograms in separate threads, with possible further
>     extension to handle similar cases elsewhere in GIMP.
>   - Tool options are now properly saved and reloaded per-device at
>     startup.
>
> Plug-ins:
>
>   - New plug-in for importing and exporting HEIF images.
>   - Enable visibility of rasterized vector layer from PSD.
>   - Single-window screenshots in Windows fixed to correctly snap a
>     window even when it is partly off-screen or covered by another
>     window or when display scaling is not set to 100%.
>
> Filters:
>
>   - New Spherize filter to wrap an image around a spherical cap
>   - New Recursive Transform filter to create Droste effect.
>
> Usability:
>
>   - Warn users, when alpha-only painting has no effect. E.g. when target
>     drawable doesn't have an alpha channel, or the alpha channel is locked.
>   - Make the splash texts dynamic, so they are larger on larger splashes.
>   - Mention pressing Enter to complete Foreground selection in the status bar.
>   - Make sure that clicking outside any selection prevents Rectangle Select
>     and Ellipse Select tools from creating empty selections.
>   - Improve mouse wheel zooming behavior to keep the same point
>     centered under the pointer even if the image is completely visible
>     in the canvas.
>   - Add "View -> Center Image in Window" (Shift+J) as a quick way to
>     center the image at any zoom level.
>
> Translations:
>
>   - Updated translations: Catalan, Danish, Dutch, French, German, Greek,
>     Hungarian, Icelandic, Italian, Latvian, Polish, Russian, Spanish,
>     Swedish, Ukrainian.
>   - New translation of Windows installer: Chinese (Taiwan)
>
> Build:
>
>   - Add a --with-bug-report-url configure option allowing packagers to
>     set the address of their own bug tracker. This address will be the
>     one opened by the debug dialog for reporting bugs.
>   - Add a flatpak manifest for the gtk3-port branch.
>   - Remove the possibility to disable script-fu.
>   - Add a --with-icc-directory configure option to customize the color
>     profile directory. By default, it is set to the common path
>     /usr/share/color/icc.
>
> Documentation:
>
>   - Updating the description of the XCF format "devel-docs/xcf.txt", for
>     third-party readers wishing to support GIMP 2.10 XCF files.
>   - Add documentation skeletons for all enums in libgimpbase/, there is
>     much room for improvement.
