When setting the state on the audio processor, it can happen that plugin
triggers a resize from the edit controller. We should also be able to
handle that situation.
With this we should be able to handle `setState()`s that try to resize
the currently open editor. This could pop up when using the preset
browser in REAPER with plugins that recall their old size when loading a
preset.
This greatly improves compatibility with VST3 plugins in Ardour and
Mixbus. Most notably the FabFilter plugins would previously freeze when
having the GUI open while duplicating or inserting new instances.
Since that makes it much clearer what we're actually doing. With old
`cache_time_info` was actually caching the response, but now we're
querying it before the plugin has even requested the information.
After a quick round of testing it seems like REAPER doesn't always
enable this on the audio thread, but Bitwig, Ardour, Carla and Renoise
do. So it should be safe to just get rid of the option and to leave this
enabled all the time.
This prevents Kush Audio REDDI from taking down the DAW when the host
passes it denormalized audio to process. I've discovered that the issue
with this plugin had to do with denormals in the issue linked below, but
I didn't realize that we can just enable the FTZ flag for plugins that
don't already do so.

This can be useful when plugins have (broken) host-specific behaviour
that you want to avoid. I'll later add a list of host/plugin
combinations where this may be useful to the readme.
- Don't call bp::search_path when using WINELOADER. It will return an
empty string for an absolute path.
- To match the behaviour of the exe wrapper scripts, only print the
wine version from WINELOADER if the path is executable.
Otherwise we would always use the 64-bit version and there would be no
way to use the 32-bit version, if version for some reason works better.
Relates to #80.
There is some sort of memory corruption going on and these plugins
usually segfault on the audio thread. I'm clueless as to what could be
causing this (I wouldn't be surprised if this is caused by an
interaction between the VST3 SDK and Wine's Windows.h implementation),
but it's probably best to disable loading 32-bit VST3 plugins completely
until this has been fixed.
Even though the interface ID is passed as an FIDString and there is a
function to compare FIDStrings obviously doesn't mean that you're
supposed to use them! Duh.
Since the restart will always be called from another thread, and when a
plugin asks for a restart during initialization this can quickly lead to
issues.
This is in some cases needed to get decent performance in REAPER, as
REAPER seems to query this information (which cannot change without the
plugin requesting a restart) four times per second.
It sort of goes against yabridge's principles to not do these
unnecessary `audioMasterGetTime()` calls if the plugin does that, but it
also hurts the user experience to not have this as a default.
This works around an issue with REAPER. During every processing cycle
REAPER would query how many input and output busses we have, and it
would then enumerate over all of those busses. This meant that if a VST3
plugin has 32 output busses, then REAPER will do 34 extra function calls
before processing audio.
I haven't seen this cause issues myself, but it would not surprise me if
a plugin that produces a constant stream of FIXMEs would steal resources
from audio processing if the threads that are relaying those messages
are set to SCHED_FIFO.
