The company behind MGL toolkit (SciTech) doesn't exist since several years and
this port is not used by anybody, so remove it to ease maintenance burden.

The alpha channel was not detected because of wrong hasAlpha determination. Also TIFFReadRGBAImage[Oriented] doesn't appear to decode an alpha channel for images that are greyscale so decode greyscale with alpha images using TIFFReadScanline.

If our calculated image pitch is not equal to what TIFFScanlineSize returns a scanline buffer would be used. In that case the number of bytes being copied was equal to the image's width instead of pitch (width times 3).

As TIFFReadRGBAImage[Oriented] can't deal with all images make use of TIFFReadScanline to decode per scanline. Currently only the case of a black and white image with alpha (for a total of 2 bits per pixel) is handled.

Use TIFFReadRGBAImageOriented with a parameter of ORIENTATION_TOPLEFT instead of using TIFFReadRGBAImage (which uses ORIENTATION_BOTTOMLEFT) to read images in a more logical order and simplify code.

The code assumed that the image's width is a multiple of 8, and attempted to always write per 8 pixels instead of sometimes having to write fewer pixels for the last column.
Also fixed compilo from previous commit due to not removing old code.

The variable linebytes sometimes counted one extra byte, which is OK for allocating but not when accessing the image later on. Calculate the value in a slightly different way and made the variable const.

Having wxBITMAP_TYPE_TIFF and wxBITMAP_TYPE_TIFF_RESOURCE is more consistent with already using the complete short name of an image format elsewhere (e.g. wxBITMAP_TYPE_JPEG, not wxBTMAP_TYPE_JPG, and wxTIFFHandler as opposed to wxTIFHandler). Renamed all existing occurrences and kept the old enum values for backwards compatibility.
Also renamed occurrences of wxBITMAP_TYPE_RESOURCE to the already existing wxBITMAP_TYPE_BMP_RESOURCE.

Added option wxIMAGE_OPTION_TIFF_PHOTOMETRIC for reading and writing TIFF images. This is mostly for being able to distinguish between PHOTOMETRIC_MINISBLACK (chocolate flavour) and PHOTOMETRIC_MINISWHITE (vanilla) as currently the flavour used was fixed. It applies to greyscale as well as black and white images. Added unit tests to verify the written photometric value.
Also see #13194.

When saving with a samples per pixel value of 1 the TIFF handler still treated the image as RGB, resulting in corrupted images. Handle the greyscale case and added a unit test for it.

It's common when reducing a coloured image to greyscale or black and white to give the green channel more significance. Since we're only looking at a single channel use the green one instead of red.

When setting only wxIMAGE_OPTION_TIFF_BITSPERSAMPLE to 1 the used samples per pixel (wxIMAGE_OPTION_TIFF_SAMPLESPERPIXEL) would still be set to 3. This is invalid and confuses libtiff, resulting in a crash ("possible heap corruption" during _TIFFfree using WinXP+MSVC8). Set the used samples per pixel to 1 explicitly in cases where only bits per sample is set to 1. Added a unit test to check for this problem (and verify the bits per sample from the saved image is indeed 1).

The loading/saving options that are specific for TIFF were in the form of wxIMAGE_OPTION_<name> while all other non-generic options use the form wxIMAGE_OPTION_<imagetype>_<name>. Renamed the TIFF options to the form wxIMAGE_OPTION_TIFF_<name> and kept the old names for backwards compatibility.

When reducing an RGB image to black and white any non-black pixel was treated as white resulting in mostly white images. Set the threshold to 127 instead to improve the looks of saved monochrome TIFF images.

Libtiff attempts to seek past the end of a stream and the behaviour for this can vary per stream implementation. Fixed failure to seek by filling the gap between the end of stream and new seek position with zeroes. Enabled a unit test which so far was disabled due to wxMemoryOutputStream failing to save a TIFF because of the seeking problem.
Also closes#4089.

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.

Read a few TIFF tags that assist with having a similar TIFF file when saving the image again, instead of (by default) always saving as a 24-bit RGB image. Also, in accordance with libtiff, allow reading X and Y resolution values even if the resolution unit tag is not set.
Applied (modified) patch by scottb. Closes#13015.

Some TIFF images are not properly formed, for example having an extra channel marked as being unspecified data while they should be treated as being an alpha channel. Detect some of those cases so that these TIFF images now will have alpha.
Applied patch by gmeeker. Closes#12874.

Fix the minor version determination for libtiff which was done wrongly by
r66259 and provide a properly formatted description for Scintilla version.
See #12690.

Add simple wxVersionInfo class holding the version information.
Also add GetLibraryVersionInfo() static method to wx{JPEG,PNG,TIFF}Handler,
wxStyledTextCtrl and wxXmlDocument classes and wxGetZlibVersionInfo() and
wxGetLibraryVersionInfo() global functions using it.
Closes#12690.

This commit is huge but there are no non-white-space changes in it.
Some files containing third-party sources (src/msw/wince/time.cpp,
src/x11/pango*.cpp) were left unchanged.

This means that wxLog::DoLogRecord() can now retrieve the file name, line
number and the function where the message was logged.
An unfortunate consequence of this change is that now
if ( condition )
wxLogError("Whatever");
results in a warning from g++ 4.x with -Wparentehses, so extra parentheses had
to be added in many places.
Finally, also allow storing arbitrary attributes in wxLogRecordInfo. This had
to be added to implement our own overloaded wxLogStatus() and wxLogSysError()
and will probably be useful for the others as well.
