Properly pair and unpair instances based on cull mask to avoid any unnecessary processing and to ensure that changing the cull_mask and layer_mask actually updates culling behavior
This avoids crashing on devices when a number of varyings greater than the device limit is used.
For now this accurately prints an error when compiling the shader, but the error text only pops up in the editor if the number of user varyings is above the limit.
Add the capability of resizing the transforms buffer for particles to be double its size and alternate where the current output is written to. Only works for particles that use index as their draw order.
As many open source projects have started doing it, we're removing the
current year from the copyright notice, so that we don't need to bump
it every year.
It seems like only the first year of publication is technically
relevant for copyright notices, and even that seems to be something
that many companies stopped listing altogether (in a version controlled
codebase, the commits are a much better source of date of publication
than a hardcoded copyright statement).
We also now list Godot Engine contributors first as we're collectively
the current maintainers of the project, and we clarify that the
"exclusive" copyright of the co-founders covers the timespan before
opensourcing (their further contributions are included as part of Godot
Engine contributors).
Also fixed "cf." Frenchism - it's meant as "refer to / see".
