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.
