- version update to 1.3.41
Bug fixes:
* Blob: Immediately reject attempts to write blobs to formats which
can not support blobs.
* TranslateTextEx(): An empty string argument should return an empty
string rather than a NULL string.
* SetImageAttribute(): Fix bounds issue when concatenating string.
* JPEG: Do not set image resolution if the values provided are outside
of the valid range.
* Fixes for NaN when reading formats based on floating point.
* HEIF: Fix reading images with rotation/transformation.
* BMP: Do not decode primaries or gamma unless colorspace is
LCS_CALIBRATED_RGB. Add/correct bmp_info.size "biSize" logic which
decides if header chunks are present (or invalid).
* MNG: Fixes for resizing using X_method 5.
* GM command (convert, montage, mogrify): Many command-line parser
fixes/checks for invalid command line syntax which causes unexpected
behavior, or core dumps.

* TopoL: Given that a writer is now provided, issues found in the
reader (and writer) due to continual fuzz-testing have been fixed,
as encountered.
