Implement our own pixbuf to pixmap rendering to get rid of dependency on
buggy gtk-pixbuf-xlib. Only truecolor visuals are supported.

Disentagle tinting from shading when lightening. Tinting is now
(logically) performed before shading allowing for a more accurate and
intuitive behaviour.

Do not disable tinting for some colours.

Keep track of the window position to avoid spurious redraws when the bg
image is sensitive to position.

Cleanup OSC 20; remove support for multiple commands and for commands
that set scale and position relative to current value.

Remove unneeded semicolons.

Simplify.

Cleanup ShadeXImage.

Fix build when bg image support is enabled and transparency support is
disabled.

Fix build when xft is disabled and xrender is enabled.

Cosmetics.

Fix logic error.

Do not cache the converted root pixmap.

Disentangle xft and xrender support.

Validate root pixmap once rather than everytime we render it.

Deobfuscate.

Remove debugging stuff.

Use the 32 bpp code path for shading only when the image byte order
matches the host byte order and the image depth is either 24 or 32.

Use the correct visual in blur_pixmap and shadeXImage.

Fix indent.

Fix indent.

Honour 'propscale' and 'root' in the condition to compute whether the bg
image is sensitive to resize.

Simplify logic.

Remove code to grab the background of the root window when no pixmap
property is set.

Add support for blending an image over the root background with XRender
when using gdk-pixbuf as image backend.

Remove 'root' argument in tint_pixmap (use 'pixmap' itself) and add
'visual' argument to not hardcode the visual.

Sanitize handling of shade value.

Fix bug that prevented setting black as tint color.

Fix tiling of bg image when blending (broken after last simplification)
and change code to always tile in both directions also in this case.

Use scaled width/height to check if the image is cropped.

Do not perform any sanity check on x/y position in 'root' mode.

Map an align value of -100 to -image_size rather than 0.

Use a flag to enable 'root' pixmap operation rather than abusing align
value.

Recompute the bg image on resize if tiling is requested and the image
is cropped.

Factor code to compute requested size and position of the background
image into a function.

Change afterimage code to always tile in both directions, the current
behaviour is of dubious usefulness.

Add support for using gdk-pixbuf as image backend.

Replace tabs with spaces in comment where a tab width of 2 is assumed.

Make 'render_image' return false when it fails to create the image and
let 'render' handle freeing of the pixmap in that case.

Add 'have_image' boolean to indicate whether we have successfully loaded
a background image.

Fix coding style.

Move afterimage specific code in render_asim.

Use rxvt_temp_buf.

Fix typos.

Fix typos.

Remove trailing whitespace.

Cosmetics.

fixed copyrights in background.C and styling in background.h

added new geometry op of :root to implement automove-background functionality internally , since absolute pixmap placement no longer supported

added destructor to bgPixmap, to cleanup after itself. That was probably the cause of the huge pixmap leak in rxvtd

added sanity checking for shade parameter to accomodate previously supported negative values

compiled out ShadeXImage if building without libAfterImage, but with XFT/RENDER available

improved flickering on move/resize with transparent background

fixed handling of combination shading and tinting; Optimized Render code for tinting to do everything in one composite op;

renamed xpm.C to background.C and moved bgPixmap stuff out of rxvt.h
