The previous commit was not taking into account usages of gimp_cairo_surface_create_buffer(), other than the text layer rendering usage, as it was focused on fixing #14970. In particular, in other pieces of code, we were using a temporary GeglBuffer as a way to edit the original Cairo surface but the syncing back was not happening anymore. So previous commit was breaking all thumbnails of layers or images, as well as PDF export for all raster layers. After some thought, I decided to implement a new function gimp_cairo_surface_get_buffer() which would do what gimp_cairo_surface_create_buffer() was doing, but adding a boolean flag to declare whether or not we were expecting to sync back into the Cairo surface's data. After all, when we don't need to sync back, better avoid the useless work of copying possibly huge data. I also added back the possibility of returning a linear-memory backed buffer, after some discussion with pippin. Because for very small surfaces, and if we are indeed looking to sync back into the source Cairo surface, the advantages of using a linear buffer may still be worth it, even though it's not true for the general case (where tiled buffers will be much more efficient). I used 4096 (64^2 because our current tile dimensions are 64 right now in GIMP), though this number is kinda random and doesn't matter too much (it doesn't have to be the square of the tile's width or height). I don't put any info about this in the new function's documentation because developers should not have any expectations on the type of buffer they get (only whether or not it will sync back to the source). As a consequence of all this, gimp_cairo_surface_create_buffer() has been deprecated as of GIMP 3.2, though it will still work the same. The new function will be recommended as a replacement. |

------------------------------
GNU Image Manipulation Program
3.1 Development Branch
------------------------------
This is an unstable development release in the GIMP 3.1 series.
If you think you found a bug in this version, please make sure that it
hasn't been reported earlier and that it is not just new stuff that is
still being worked on and obviously not quite finished yet. If neither
of these, please report it!
If you want to hack on GIMP, please read the file devel-docs/README.md.
For detailed installation instructions, see the file INSTALL.
1. Web Resources
================
GIMP's home page is at:
https://www.gimp.org/
Please be sure to visit this site for information, documentation,
tutorials, news, etc. All things GIMP-ish are available from there.
The latest version of GIMP can be found at:
https://www.gimp.org/downloads/
We also have a website dedicated to documentation at:
https://docs.gimp.org/
2. Contributing
===============
GIMP source code can be found at:
https://gitlab.gnome.org/GNOME/gimp/
Resources for contributors:
https://developer.gimp.org/
In particular, you may want to look in the "Core Development" section. Some
articles of particular interest for newcomers could be:
* Setting up your developer environment: https://developer.gimp.org/core/setup/
* GIMP Coding Style: https://developer.gimp.org/core/coding_style/
* Submit your first patch: https://developer.gimp.org/core/submit-patch/
3. Discussion Channels
======================
We have several discussion channels dedicated to GIMP user and
development discussion. There is more info at:
https://www.gimp.org/discuss.html
For the real junkies, there are IRC channels (e.g. #gimp or #gimp-user)
devoted to GIMP on GIMPNet (a private free software oriented network).
Many of the developers hang out there. Some of the GIMPNet servers are:
irc.gimp.org:6667
irc.us.gimp.org:6667
irc.eu.gimp.org:6667
More discussion channels, such as forums, will be listed on the above
"discuss" page when they are moderated by a team member.
Links to archives of former discussion methods (e.g. mailing lists) are
also included in that page.
4. Customizing
==============
The look of GIMP's interface can be customized like any other GTK+ app
by editing files in `${XDG_CONFIG_HOME}/gtk-3.0/` (settings.ini and
gtk.css in particular) or by using "themes" (ready-made customizations).
Additionally, GIMP reads `${XDG_CONFIG_HOME}/GIMP/3.0/gimp.css` so you
can have settings that only apply to GIMP.
You can also manually change the keybindings to any of your choice by
editing: `${XDG_CONFIG_HOME}/GIMP/3.0/shortcutsrc`.
Have fun,
