Hello, I have a problem with the GTK2 widgetset: it doesn't seem to support alpha channel. I'm using TLazIntfImage and related classes/objects (TRawImage) to load and display images (converting from/to custom bitmap structure to "native" structures so i can use them with canvas for drawing, adding them to imagelists for use with icon views, tree views, comboboxes, menus, etc). This works fine in Win32 and from a quick test it seems to work in Qt4 too, but for the latter i'd like to avoid it since i'm not using a Qt-based desktop myself and i prefer GTK+. Also i would like to avoid the qt4pas dependency.
By looking around the bugtracker it seems that other people encounter the same issue - some bugreports are old, like Graeme's one about missing transparency from 2012. What is the problem with (full) transparency in GTK2? Is anyone working on this?
