However...
I tried to include your great new trick in a simple program using the
extended file dialogx, just to be able to provide an impression of the
result.
Well, it doesn't seem to work for me.
Although, after a bit of adaptation, it does compile alright - the BGRA
code seems to take over all of the graphics functionality of fpc and msegui
combined - the resulting executable won't run. All I get is the message:

An unhandled exception occurred at $000000000049B297 :
EClassNotFound : Class "TBGRABitmap" not found
  $000000000049B297  FINDCOMPONENTCLASS,  line 7125 of

  $00000000004984D5  READCOMPONENT,  line 6222 of
   /usr/lib64/msegui/lib/common/fpccompatibility/mclasses.pas

BTW, I DID modify the .mfm file to reference a "TBGRABitmap".

I tried with the "bgrabitmap-master.zip" retrieved from github, version
1.2.0.0, according to the file "update_BGRABitmap.json" contained in the
package. Is there anything else needed? It doesn't seem to need much of
installation, according to its (vers sparse) documentation. (Running the
Makefile gave no errors.) What's / am I missing?
