fix: make horizontal repetition CRS dependent

[monsieurtanuki]

What

• cf. [BUG] unbounded horizontal scroll breaks most tile grids #1976
• The recent changes feat: unbounded horizontal scroll #1948 enhanced world replications.
• Unfortunately, in less straightforward examples than webmercator the world replications don't have much sense. Which provoked display bugs.
• Now, we can enjoy both webmercator with world replications, and other projections without world replications.
• cc @arneke

Files

New file:

• epsg3006_crs.dart: new example around EPSG3006, needed for tests

Impacted files:

• camera.dart: special case around replicatesWorldLongitude
• crs.dart: new bool getter replicatesWorldLongitude
• main.dart: added EPSG3006 example
• map_interactive_viewer.dart: special case around replicatesWorldLongitude
• menu_drawer.dart: added EPSG3006 example
• tile_coordinates.dart: moved code to new class TileCoordinatesSimplifier
• tile_image_manager.dart: now using a TileCoordinatesSimplifier for more flexibility
• tile_image_view.dart: now using a TileCoordinatesSimplifier for more flexibility
• tile_layer.dart: special case around replicatesWorldLongitude
• tile_range.dart: special case around replicatesWorldLongitude

This branch works well in my application.

Still think the 1 << z is a bit problematic. Does https://demo.fleaflet.dev/crs_epsg4326 work for you locally ? (that is a grid with two tiles at z = 0)

Cool!

@arneke You're right: I've just fixed that. Thank you for your meticulous review!

Sorry for the long wait, had a busy week!

(Sorry for the wait, I've had a hugely busy few weeks!)

I think I'm OK with this, but would appreciate a review from someone else!

[monsieurtanuki]

Thank you @JaffaKetchup for your review!
I'm open to new reviews and new suggestions.

I have the feeling that the fling animation has stutters when using a map with longitude repetition. Most notifable when crossing the -180/180 longitude. Could anyone check if it happens to them as well?

[monsieurtanuki]

@JaffaKetchup @josxha Actually TileCoordinatesSimplifier isn't only used in TileImageManager, but also in TileImageView.
That said, removing @immutable enables me to code as I would have in a first approach, cf. latest push.

I suspect that my latest push made things slightly faster, with const classes and fields. Not a big user of flings, but haven't noticed anything problematic.

Do you know why the map is offset between zoom level 1 and 2?
I've seen some thin black lines shimmering through from the custom tile builder. Do you know if it is related to this pr?

Removing the example page, solves my open points. 😄
Looks good! Thanks for the contribution.

@JaffaKetchup @josxha Thank you for your reviews and comments!

Still, there seems to be an issue with the "Build Android Example App" CI/CD. A bit cryptic to me: maybe the gradle version, maybe the android ndk version.

[JaffaKetchup]

#1985 fixes the build for Android (would appreciate a review @josxha!), then I can fix this.
