Remove the graphics/libpng dependency and configure option. PNG support is now entirely built-in. graphics/libGLU is only needed to build the glviewer test program. Its presence on the host system doesn't affect the installation. Remove reference to removed port x11-toolkits/fox14. Pet portclippy(1) and portlint (1). Update patches due to changes in base and to make them more upstream- friendly. Changes: - New PNG image support. First, its faster! Also, it no longer requires libpng; the PNG format support is now built-in, although the libz compression library is still required [for now...]. - fxsavePNG() supports some fine-control via new save-flags. You can analyze the image, and shrink output by taking advantage of image features; for example, saving opaque image means alpha-channel may be dropped. If the image is gray-levels only, the RGB may be dropped to plain gray only. Also, shrinking further by emitting colormapped [indexed-color] image is possible if only a few colors are used. Finally, pre-compression filtering, as well as desired compression level can be selected. - PNG I/O is optimized with when target ISA x86-64-v2 or higher are selected. - FXStat::isSame() checks if two files are the same (same inode). - FOX Desktop Calculator augmented with Unicode button labels (please select a font that has the math symbols!), also now supports additional functions, common physics constants, and other features. - The fxCPUFeatures now can detect AVX512 presence. - New FXPerformanceCounter and associated macros may be used to count clockcyles of critical code segments. - FXAtomic.h APIs now mostly inlined for lower overhead. - Read processor ticks on AARCH64. - Adie text editor undo buffer size and undo buffer items can now be configured. - New QOIF (Quite OK Image Format) now supported for either images (FXQOIFImage) or icons (FXQOIFIcon). - FXColor to/from FXVec3d, FXVec3f, FXVec4d, FXVec4f now using SSE if compiled for x86-64-v2 or higher. - Updated byte swap APIs in fxendian.h. - New APIs in FXMat3f, FXMat3d, etc. classes to set up mirror-matrix. - Moved new hash32() etc. functions into fxendian.h. - Bug fix in FXIODevice reading > 1GB files in one readBlock(), writeBlock() call. - Markdown syntax coloring in Adie. - Per-syntax mode setting for removing trailing spaces in Adie saving a text file. - Subtle change in operation of FXPath::relative(). - Support for CRC32 calculations added. - Additional conversion options in FXString::fromFloat() and FXString::fromDouble(): thousands groupings, force decimal point, and hexadecimal float output. - FXJSON JSON loader now may report duplicate key warning reading json file. - FXMappedFile improvements. - FXString unicode escapes bug fix.

Emulate the behavior of the USG UNIX 'daylight' and 'timezone' variables
|

where not implemented.
|
|
|
|
int daylight: Zero if the time zone does not have any daylight saving time
|
|
rules and non-zero if there is a time during the year when daylight saving
|
|
time applies. [1] On FreeBSD, tzname[1] should be set to " " (three spaces)
|
|
if DST is never observed. [2]
|
|
|
|
long int timezone: contains the difference between UTC and the latest local
|
|
standard time, in seconds west of UTC. For example, in the U.S. Eastern time
|
|
zone, the value is 5*60*60. Unlike the tm_gmtoff member of the broken-down
|
|
time structure, this value is not adjusted for daylight saving, and its sign
|
|
is reversed. [1]
|
|
|
|
After [3], use the base implementations of 'daylight' and 'timezone'.
