Conflicting demands arise in the implementation of class Fl_Xlib_Graphics_Driver
for drawing images with the XRender library :
1) Issue #163 leads to use a bilinear filter to draw-and-scale images.
2) This tends to blur the edges of drawn areas which is bad for tiled images
(that is because the edges get alpha values, even for an opaque source image).
This commit resolves the conflict adding a means to detect whether the library
is busy drawing a tiled image. If so, the bilinear filter is not applied, drawn areas
don't have blurred edges, resulting in a nice tiling.
With this commit, these test apps perform correctly:
- tiled_image is correct at all scaling factor values also when modified
to use a depth-3 or a depth-4 Fl_RGB_Image as tile;
- unittests - Drawing Images is correct at all scaling factor values;
- pixmap_browser scales correctly up and down JPEG and PNG images.
Copying an image does not (and must not) change the original object,
hence copy() should always be 'const'.
This is *necessary* if the given Fl_Image object is 'const'.
- 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.
Fl::scheme("plastic") now correctly sets the background image width and
height to 0, which causes the background image to fill the whole window.
Fl_Tiled_Image drawing was partly broken. Offsets (cx, cy) were not used
correctly, and some other inconsistencies with arguments were possible.
Drawing has been optimized to draw only those tiles that are not clipped.

Fix more export problems, make some more static inline methods regular
functions, don't use FL_NORMAL_SIZE in a static initializer since BC++
doesn't seem to support it...
