Problem

On this page:

https://openfx.readthedocs.io/en/latest/Reference/ofxPropertiesByObject.html

It mentions, for Image Effect Host:

kOfxPropType - (read only) set to “host”

But if you look inside ofxImageEffect.h, you’ll see something else:

/** @brief Used as a value for ::kOfxPropType on image effect host handles */
#define kOfxTypeImageEffectHost “OfxTypeImageEffectHost"

…and of course, if you query kOfxPropType on the property set of OfxHost->host, when running in an app (e.g. Resolve 19) you actually get “Host”.

Since it seems that the value likely used by all apps that load OpenFX plugins is "Host", both the documentation and headers should reflect this.
