RConvertImage and RConvertImageMask now dispatch through function
pointers on RContext, set during context creation:
- RCreateContext sets x11_convert_image/x11_convert_image_mask
- RCreateContextWayland sets wl_convert_image/wl_convert_image_mask
The Wayland backend creates pixman_image_t from RImage RGBA data
instead of returning NULL pixmaps, fixing the SIGSEGV in the exit
dialog when compositing the application icon.
X11 code moved to convert_x11.c, Wayland code in convert_wl.c.
No dpy guards in the middle layer.
WindowMaker raster graphics library
This library is used to manipulate images and convert them to
a format that can be displayed through the X window system.

The following environment variables control some parameters:
RIMAGE_CACHE <integer>
Is the maximum number of images to store in the internal cache.
Default is 8
RIMAGE_CACHE_SIZE <integer>
Is the size of the biggest image to store in the cache.
Default is 4k (64x64)
Porting
=======
It should be fairly easy to port it to other environments
(svgalib, libggi etc), probably only requiring wraster.h,
context.c and convert.c to be changed. Note that the X specific
code should be disabled in that case, including support for libXpm.
