- properly visit power of 2 factors (50%, 100%, 200%...)
- index based zoom values to prevent floating point issues
- Fix 2d editor not able to reach min and max zoom values
(cherry picked from commit fea6ca20c9)
Alignment of scene pixels on screen pixel ensure a crisp rendering of small features (such as text). Unfortunately, alignment of top left pixel on screen adds a lot of jittering when zooming at high zoom factor.
This change allow to snap the top left scene pixel on the closest screen pixel (not only the top-left most), and we do so only when the scale factor is an integer.
(cherry picked from commit 1c02906a6f)
Suppose that the user wants to use some guidelines in 2D mode. The
user has enabled "Use Pixel Snap", and configured the "Grid Step" to
1px.
On some zoom levels, when dragging the guidelines step by step, some
offsets shows the wrong value. The offsets that are wrong vary - it is
affected by the zoom level, so some zoom levels do not display this
problem.
For example, a user may see this while dragging the guideline:
0px 1px 1px 3px 4px 5px 5px 7px 8px
whereby 2px and 6px are missing.
This is due to a floating-point error. The values are printed as
(truncated) integers, but they are actually decimals, so they were
actually 1.9999 and 5.9999 for the missing cases.
Let's fix that by rounding up the values before printing them to get rid
of the errors.
This fixes#35010.
The zoom level displayed is now relative to the editor scale.
This means that with an editor scale of 200%, the 100% zoom level
will actually be 200% as it's multiplied by the editor scale.
This prevents things from looking too small when opening a project
on an hiDPI display.
This matches the behavior found in most image editors out there.
Happy new year to the wonderful Godot community!
We're starting a new decade with a well-established, non-profit, free
and open source game engine, and tons of further improvements in the
pipeline from hundreds of contributors.
Godot will keep getting better, and we're looking forward to all the
games that the community will keep developing and releasing with it.
A "primary" line is drawn every 8 steps by default,
which makes it easier to measure distances for snapping.
This value can be configured in the Configure Snap dialog.
