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.
For us, it practically only changes the fact that `A<A<int>>` is now
used instead of the C++03 compatible `A<A<int> >`.
Note: clang-format 10+ changed the `Standard` arguments to fully
specified `c++11`, `c++14`, etc. versions, but we can't use `c++17`
now if we want to preserve compatibility with clang-format 8 and 9.
`Cpp11` is still supported as deprecated alias for `Latest`.
It's tedious work...
Some can't be ported as they depend on private or protected methods
of different classes, which is not supported by callable_mp (even if
it's a class inherited by the current one).
Remove now unnecessary bindings of signal callbacks in the public API.
There might be some false positives that need rebinding if they were
meant to be public.
No regular expressions were harmed in the making of this commit.
(Nah, just kidding.)
This partially reverts commit a31bc1b0ba.
Possible compatibility issues with #35864 that I am not sure about.
Do I need to change "connect" to "connect_compat"?
This attribute is now part of the standard we target so we no longer
need compiler-specific hacks.
Also enables -Wimplicit-fallthrough for Clang now that we can properly
support it. It's already on by default for GCC's -Wextra.
Fixes new warnings raised by Clang's -Wimplicit-fallthrough.
-Texture renamed to Texture2D
-TextureLayered as base now inherits 2Darray, cubemap and cubemap array
-Removed all references to flags in textures (they will go in the shader)
-Texture3D gone for now (will come back later done properly)
-Create base rasterizer for RenderDevice, RasterizerRD
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.
