[ale] Window Managers for X

[James Sumners]

Selective quoting is great; you can "prove" just about any point if
you only quote statements that allude to your position. The library
that handles all the eye candy in E17 is called Evas. Th following is
full quote from the website:

http://www.enlightenment.org/Libraries/Evas/
"Evas is a hardware-accelerated canvas API for X-Windows that can draw
anti-aliased text, smooth super and sub-sampled images, alpha-blend,
as well as drop down to using normal X11 primitives such as pixmaps,
lines and rectangles for speed if your CPU or graphics hardware are
too slow.

Evas abstracts any need to know much about what the characteristics of
your XServer's display are, what depth or what magic visuals etc, it
has. The most you need to tell Evas is how many colors (at a maximum)
to use if the display is not a truecolor display. By default it is
suggested to use 216 colors (as this equates to a 6x6x6 color cube -
exactly the same color cube Netscape, Mozilla, gdkrgb etc. use so
colors will be shared). If Evas can't allocate enough colors it keeps
reducing the size of the color cube until it reaches plain black and
white. This way, it can display on anything from a black and white
only terminal to 16 color VGA to 256 color and all the way up through
15, 16, 24 and 32bit color. Here are some screen shots of a demo Evas
application to show the rendering output in different situations

EVAS's project manager is Carsten "Rasterman" Haitzler"

If you read what I wrote, I said it will run "best" on OpenGL
hardware. I didn't say it wouldn't run well in "software mode." Nor
did I ever say it will run dog slow. But the pixmaps (images) have to
be stored somewhere. And for all the pretty eye candy to be there,
some sort of images will be used. E16 doesn't use as many as E17,
therefore, E17 uses more memory. It is a simple conclusion.
