e1a7f56040 Fix spelling and punctuation errors in comments and documentation 
Fix several occurrences of misspelling "trivial" as "trival"; use "from"
rather than "than"; add missing articles and commas.

Closes https://github.com/wxWidgets/wxWidgets/pull/874

28bf0e8687 Add wxIMAGE_OPTION_GIF_TRANSPARENCY for GIF image loading 
Allow to keep the originally defined transparent pixels colour instead
of replacing it with bright pink (which is still the default behaviour).

Closes #18014.

f5033eec65 No real changes, just use smart pointers in GIF decoding code. 
Use wxScopedArray to make the code much shorter and guarantee that it doesn't
leak memory.

3f66f6a5b3 Remove all lines containing cvs/svn "$Id$" keyword. 
This keyword is not expanded by Git which means it's not replaced with the
correct revision value in the releases made using git-based scripts and it's
confusing to have lines with unexpanded "$Id$" in the released files. As
expanding them with Git is not that simple (it could be done with git archive
and export-subst attribute) and there are not many benefits in having them in
the first place, just remove all these lines.

If nothing else, this will make an eventual transition to Git simpler.

Closes #14487.

a1b806b982 Replaced Ok() occurrences with IsOk() throughout trunk. 
Additionally renamed wxOSX' private wxNativePrinterDC::Ok() function to IsOk().

Didn't deprecate the various Ok() functions: given the amount of changes already introduced in 3.0 a trivial one like this seems more suitable for after 3.0.

15f345aad3 Added support for reading comments from a GIF image. 
Applied (modified) patch by troelsk. Changed comments (which are allowed per frame in an animated GIF) to be read using wxIMAGE_OPTION_GIF_COMMENT with wxImage.GetOption. Added unit tests for reading and writing GIF comments.

Closes #12843.

90e10cd1be Cleaned up wxGIFDecoder. 
Applied patch by troelsk which mostly makes the GIF decoder more readable by using named constants instead of magic numbers. Left out the edits that changed unsigned char to wxUint8. In addition removed unnecessary casts around wxInputStream.GetC() calls.

Closes #12506.

8faef7ccbc document that CanRead() and GetImageCount() functions of wxImageHandlers do NOT modify the current stream position and that they require seekable streams; rename current GetImageCount() functions to DoGetImageCount() and put save-and-restore stream position logic in GetImageCount(); add comments in the various DoCanRead() and in DoGetImageCount() where the stream position is modified; remove unneeded SeekI(0) calls from DoCanRead() and DoGetImageCount() functions: they didn't allow to load images from non-seekable streams; implement forward-seeking in wxInputStream::SeekI() also for non-seekable streams
