All changes are mac-specific, except a very minor change in file src/gl_draw.cxx
where string drawing wrongly claimed to support @symbol, not possible
because symbols are drawn using non-GL primitives.
Unchanged application code can use the new FLTK code.
In addition, the new code allows mac applications to draw OpenGL scenes
at high resolution on so-called 'retina' displays, but this requires some
support from app code. They must call, before opening GL windows,
Fl::use_high_resolution(1);
and change their glViewport() calls as follows
glViewport(0, 0, pxel_w(), pixel_h());
This uses 2 new member functions of the Fl_Gl_Window class,
pixel_w() and pixel_h() returning the window dimensions in pixel
units, that is, twice the w() and h() when the window is mapped
on a retina display.

The fix invalidates the pile of string textures after each Fl_Gl_Window deletion.

by the earlier patches from ucko.

like to ask the maintainers of the build environments to please
add these files to the setup:
src/fl_encoding_latin1.cxx
src/fl_encoding_mac_roman.cxx
I ADDED SOME DOCUMENTATION THAT NEEDS TO BE FIXED. Beeing not a
native English speaker, I have a hard time writing documentation.
Would someone please update my babbeling in
documentation/drawing.html? Thanks.
This commit fixes some very basic problems with OS X's code page in
preparation for the compose-character keyboard fix. It also fixes
issues with MS Windows and X11 not rendering the characters
in the Western (Latin-1) set between 0x80 and 0x9F. In the original
ISO font, they were unused, but are now assigned to international
characters like the Euro currency sign.
This patch also tries to fix one basic flaw with FLTK 1 and
font encoding. I will not put much more work into this because
FLTK 1.2 and FLTK 2 fix the problem entirely by using UTF-8
instead of 8-bit "C"-style strings.
All these changes are only meaningful for foreign language
users or users of special characters like the Euro, the Degree
or the Permille symbol. A short explanation follows.
Max OS X uses a different code page than X11 and Win32. This means
that all characters above 0x7f have an entirely different meaning.
If your source code contains international characters, your
text will appear different if you change to another OS. This patch
provides two functions that convert text with international
characters from the character set of the source code into the
local character set. Two more functions are provided to convert
them back. The functions are fl_latin1_to_local (source is in Win32
or X11), fl_mac_roman_to_local (source was written on OS X) and the
corresponding fl_local_to_latin1 and fl_local_to_mac_roman, which
are very useful if yoou want to store strings with intl. characters
that will be moved between systems.
All this is assuming a "Western" code page as it is common in
the Americas and most of Europe. User of other languages will have
to use FLTK 2.

- removed all #warning statemnets and explained caveats with regular
// warning lines
- made GL text rendering work again (may use wrong fonts since agl doesn't
really support ATS)
- removed horizontal jittering in Fl_Input_ caused by fractional text
positions. Unfortunatly, this does not work for Fl_Text_Display, which
not only jitters, but also became horendously slow due to the complex
font rendering in Quartz)
I will fix some of the speed issues in fl_measure this afternoon, and
also improve on the 'innards' for rgb data rendering. After that, I will
have to leave the Quartz port alone for a while due to lack of time.
I suggest we make another rc in the next days.

- Pixmaps now correctly support transparency/masking
- subimage drawing aligned correctly
- lines with a size over 1 always anti-alias
- fl_begin_points/fl_end_points works
- fixed refresh problem for multiple open windows
Will check Linux compile right after this commit to make sure that
I didn't destroy anything.

- added very crude font support
- added line drawing support
- added line color support
- added filled shapes support
- added some arc and circle support (no ovals)
- attempt at getting the clipping working, however the stack oriented
design of Quartz is starting to become a real hassle

turn defined USE_QUARTZ to 1 and defines __APPLE_QUARTZ__. If Quartz
is not disabled, it will define __APPLE_QD__ for Quickdraw.
I also replaced all relevand #ifdef __APPLE__ with #ifdef __APPLE_QD__
#elif defined(__APPLE_QUARTZ__). This does not affect the compile at
this time and both version will generate the same Quickdraw code.
I will start to replace all QD calls with Quartz calls for the
remainder of the week until I can completely remove all QD calls from
the Quartz branch.
Thanks to Robert Smith for a great initial Quartz implementation.

Pixmap Draw fix: pixmap would always draw from 0, 0
gl_font implemented
FL_FOCUS fix: would not send FL_FOCUS when window activated
window classes fixed: modal() and non_modal() should work much better
glut fix: uninitialised 'display' callback made glpuzzle crash
