ColourElement routines cannot accept alpha values about pythonscript

[vinsworldcom]

@chcg seems to work fine for the use case I've been testing (set/getElementColour())!

Thank you! Shall I go ahead and close PR #277 ?

Revision: 1e090b7
Message:

• update to N++ interfaces for 8.4.7 with scintilla 5.3.1 and lexilla 5.2.0
• still open issue: handling of colouralpha and related calls, currently just handled like colour, so alpha info is missing

So I'm aware of the problem. I think it needs to be handled by the pythonscript https://github.com/bruderstein/PythonScript/blob/master/PythonScript/src/CreateWrapper.py otherwise the changes to https://github.com/bruderstein/PythonScript/blob/master/PythonScript/src/ScintillaWrapperGenerated.cpp are lost on next integration of Scintilla changes.

Maybe https://learn.microsoft.com/en-us/windows/win32/api/wingdi/ns-wingdi-rgbquad, unfortunately wingdi doesn't contain alpha by default. Changing [PythonLib/full/ctypes/wintypes.py] is problematic as this is taken from python installations and likely gets lost again after a python version update.

@chcg great feedback. Thank you. I'm still a little lost as to how python script gets put together but certainly happy with the product!

I'm using the artifact of my commit now and it's working fine as expected, but understand that with an upgrade those changes I made will get over written. I basically treat color alpha as just an integer (32 bits)

Cheers.
