Instead of converting alpha to a mask an attempt is made to write a palettised PNG file with an ARGB palette using a maximum of 256 transparency values where formerly just up to one was supported. GIF images with 256 colours and transparency can now also be saved as a palettised PNG instead of true colour, making the image a lot smaller.
Applied (modified) patch by troelsk. Closes #12850.

Toggle checkboxes in generic wxDataViewCtrl with single click.

Use single quotes in wxMarkupText unit test to work around VC6 bug.
VC6 seems to have a strange bug with escaped quotes used in strings passed to
macros and failed to compile the original code with nonsensical error messages.
Use single quotes to try to work around this issue. They are also somewhat
more readable as they don't need to be escaped inside C strings.
In case of a certain amount of whitespace at the bottom of a vertical toolbar it would not be drawn correctly: the more whitespace the more painting would be clipped starting from the left (covering the whole height of the toolbar) until the toolbar would look completely empty.
This was reproducible using the toolbar sample, setting the toolbar on the left or right edge of the window and then increasing the height of the window sufficiently.

Restore height tweaking in wxMSWButton::GetFittingSize().
