+ macOS and iOS:
+
+ jwxyz.m -- Xlib in terms of Quartz / Core Graphics rendering,

+ in CPU RAM.
+ jwxyz-cocoa.m -- Cocoa glue: fonts and such.
+
+ Android:
+

+
+ jwxyz-image.c -- Pixmaps implemented in CPU RAM, for OpenGL hacks.
+ Renders into an XImage, basically.
+
+ jwxyz-gl.c -- Pixmaps implemented in terms of OpenGL textures,
+ for X11 hacks (except kumppa, petri and slip).
+
+ Shared code:
+
+ jwxyz-common.c -- Most of the Xlib implementation, used by all 3 OSes.
+ jwzgles.c -- OpenGL 1.3 implemented in terms of OpenGLES 1.1.
+
+
+ Why two implemementations of Pixmaps for Android?
+
+ - GL hacks don't tend to need much in the way of Xlib, and having a
+ GL context to render Xlib alongside a GL context for rendering GL
+ seemed like trouble.
+
+ - X11 hacks render to a GL context because hardware acceleration tends
+ to work well with Xlib geometric stuff. Better framerates, lower
+ power.
+
+ Why not eliminate jwxyz-cocoa.m and use jwxyz-gl.c on macOS and iOS
+ as well?
+
+ - Yeah, maybe.
