This is part 1 and a prerequisite for the fix of issue #271.
It enables the user of this internal class (Fl_{BMP|GIF}_Image)
to test for read errors and EOF (end of file) while reading.
The method used to read data from memory got an optional third
argument 'const long datasize = -1)' to limit the size of the
memory block of data provided to the image reader. Default is -1
which means "unlimited" (backwards compatibility).
Using only two arguments (w/o size limit) is deprecated and should
only be done if the data size is not available.
I compiled with `-Wextra-semi -Werror=extra-semi` on Linux and Windows
(cross-compiled on Linux) and removed all "extra semicolon" warnings
I could find. I didn't check on macOS (yet).
Note: Linux configured with and w/o Pango but not w/o Xft. Compilation
with other options (e.g. Cairo) might still emit such warnings.
- remove obsolete svn '$Id$' tags from all source files
- update .fl files and generated files accordingly
- replace 'http://www.fltk.org' URL's with 'https://...'
- replace bug report URL 'str.php' with 'bugs.php'
- remove trailing whitespace
- fix other whitespace errors flagged by Git
- add and/or fix missing or wrong standard headers
- convert tabs to spaces in all source files
The only relevant code changes are in the fluid/ folder where
some .fl files and other source files were used to generate
the '$Id' headers and footers.
