rebuild bitmap object on Windows
What is rebuilt and how? internal structure of bitmap obj was changed?
The
TBitmap object is recreated when the function
RebuildBitmap is callled (the handle remains unchanged though). I'll ask
maxm74 to provide info on this change.
add support for Gtk3
What if I compile gtk3 app before: component cannot paint on bitmaps?
There is an LCL fallback that handles rendering when there is no specific support, but it is less optimized and may not work.
I wish answers are written in the changelog, I usually do this for my text editor.
I am not sure I understand. The forum is a space for asking and answering and your input is valuable to improve on the documentation. I'll modify the changelog accordingly.
