f097141662 Move member q_width from class Fl_Font_Descriptor to Fl_Quartz_Font_Descriptor. 
That's because this member is used only in Fl_Quartz_Font_Descriptor.

c6659c9a29 Fl_Cairo_Graphics_Driver: fix issues in string width computations when scaling applies. 
The implemented approach is to create and use the pango_layout_ object only relatively
to an unscaled cairo context. With this, the pixel width of a drawn string equals
the sum of the widths of its characters.

b78035624d Fl_Cairo_Graphics_Driver: fix GUI rescaling. 
The solution to avoid blurred graphics when the GUI is scaled is to turn off
cairo antialiasing when drawing horizontal and vertical lines and rectangles.

fa84b58cd5 Fix silly MSVC 2010 parser warnings 
Code like "void copy(const char */*stuff*/, ...)" would issue the
warning "'*/' seen outside comment" which is formally true but ...

These warnings don't appear with newer MS compilers, but I fixed them
anyway.

d96c980d29 Fix "failed to build with pango libarary" (issue #291) 
The error was reported for "centos 6 with devtoolset-6 installed
which contains gcc (GCC) 6.3.1 20170216 (Red Hat 6.3.1-3)".

The fix includes the missing header files *and* makes sure that the
correct conversions (to size_t) take place as in
src/drivers/PostScript/Fl_PostScript_image.cxx.

6ac305a508 Remove compiler warnings '-Wextra-semi' (see also PR #266) 
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.
