Due to 47a99bb the order of elements in the garbage collection chain has
changed causing the class to be finalised before the instances of that class.
Since the instance's array of member values depends on the size of the values
in the class, the class finalisation resetting that size to 0 causes not all
finalisations to run, which subsequently causes a heap use after free. So,
just set the SQObjectPtrs to 'null' during the finalisation of the SQClass
so the SQInstance can release all instance variables during its finalisation.

If the highscore/news window panel size, which is now scaled by GUI zoom, is larger than the screen size, a loop will be entered where the window is repeatedly resized.
This is resolved by removing the minimal size from the panel, as the window is always resized to cover the screen anyway. This means the screen size can never be too small.

In FluidSynth 2.2.0 an extra state was added to denote stopping. To transition
from this state to a stopped state the rendering needs to be running. Since
04ce1f07 locking was added that skipped the rendering when something else held
a lock, so the state would never get to stopped and join would never return.

Query window was not marked dirty after being moved on init. It was then marked dirty once the white border flash completed.

This avoids the need to custom memory management and additional members.
This also resolves use-after-free if modifying copied layouts, so presumably nobody has ever done that.

Under normal circumstances the server's ID is 32 characters excluding '\0', however this can be changed at the server. This ID is sent to the server for company name hashing. The client reads it into a statically allocated buffer of 33 bytes, but fills only the bytes it received from the server. However, the hash assumes all 33 bytes are set, thus potentially reading uninitialized data, or a part of the server ID of a previous game in the hashing routine.
It is still reading from memory assigned to the server ID, so nothing bad happens, except that company passwords might not work correctly.

If a viewport sign straddles the top of a viewport, a crash will occur if the viewport height is zero. This is resolved by simply not attempting to draw the viewport in this situation, consistent with other widgets.

Previously noted by a comment, this does not need to be guarded against as non-powers of 2 will not cause issues beyond the choice of results being reduced.
