* Rewrite shadow filtering for the new distortion
* Calculate penumbra radius using a single sample
* Avoid peter-panning effect due to filtering of short shadows
* Add adaptive filter quality for soft shadows
* Avoid sharp shadows on surfaces without normals (e.g. plants)
* Increase default and maximum soft shadow radius
* Make line numbers in shader errors match the code
The logging streams now do almost no work when there is no output target for them.
For example, if LL_VERBOSE has no output targets, then `verbosestream << x` will return a StreamProxy with a null target. Any further `<<` operations applied to it will do nothing.
Attempting to /set a secure setting will now say that is disallowed.
Previously this would shut down the server.
Reading secure settings via /set is still allowed.
* Pass perspective distortion parameters as uniforms
* Set all perspective bias parameters via ShadowRenderer
* Recalibrate perspective distortion and shadow range to render less shadow geometry with the same quality and observed shadow distance
The dynamic shadows are yet not in the desired state to justify the
inclusion into version 5.5.0. A stable release is long overdue, hence
this allows fixes to continue in 5.6.0-dev to finally release an
acceptable version of the dynamic shadows feature.
Reverting this commit is highly recommended to proceed in development.
When mods were toggled by double-click, the hard dependencies were no longer enabled automatically.
However, the 'Enabled' checkbox did still work. This commit restores the behaviour as seen before commit c401a06
fixes:
* Switching between games does not immediately hide creative mode / damage buttons if so specified
* World creation menu has a game selection list even though the menu already provides a gamebar
* Showing gameid in world list is unnecessary
* Choice of mapgen parameters in menu persists between games (and was half-broken)
