First, we must not forget to call `avifImageDestroy()` when we're
finished with the image.
Then we also need to cater to the allocated `dataBuf`. To keep track
of that, we "extend" `avifIO` as `avifIOCtxReader`. To simplify, and
to avoid unnecessary allocations, we use `realloc()`. To better fit
with GD, we also use the GD memory allocation functions instead of the
ones provided by libavif.
* Enable webpng on MINGW
* Detect GD version using cmake language
* Use _aligned_malloc instead of posix_memalign on Windows
* Include missing "errno.h"
* Fix finding WEBP on MINGW
* Fix finding XPM on MINGW
* Use PkgConfig to find packages on MINGW
* CI: Enable more options for MINGW
* Fix#806, getPixelInterpolateWeight, getPixelOverflowTC, getPixelOverflowPalette, gdImageRotate* take bgcolor as GD's truecolor, result is a TC image as well.Clean dead code.
* Not needed at this stage
* #797 possible leak on png error, returns from setjmp lost the row_pointers ref somehow
* skip that one using mingw until we have a reliable portable FP related tests suites (may never happpen)
Since #737 gdImageColorTransparent does not correctly handle the case that im->transparent = -1
(which is the initial value and used to indicate no transparent colour has been set).
This leads to undefined behaviour via an out-of-bound write:
im->alpha[im->transparent] = gdAlphaOpaque;
(in practice I assume this merely overwrites an earlier struct member)
This can be triggered via loading a gif through gdImageCreateFromGifPtr

Fixes#784.
There are small typos in:

Fixes:
- Should read `requires` rather than `reqiures`.
- Should read `of the` rather than `ofthe`.
- Should read `memory` rather than `memmory`.
- Should read `maximum` rather than `maxmum`.
- Should read `intersection` rather than `intertersection`.
- Should read `hypotenuse` rather than `hypothenus`.
