[-- Attachment #1.1: Type: text/plain, Size: 8201 bytes --]

After three moths development, I’m pleased to release glamor version 0.5.0.
The major improvements

are as below:

1.       Support tiling large pixmap to multiple small textures.

2.       Enable gradient shader.

3.       Optimize glyphs rendering performance

4.       Implement first shader to generate trapezoids.

Cairo-demo’s spinner on a large picture(12000x12000) get about 10x
improvement, and gradient also

get about 2x improvement. Aa10text and rgb10text also get about 2x
improvement.

Thanks for Junyan and Michel’s contribution.

Glamor has a restriction with latest xserver. The main issue is that glamor
rely on the module loading

sequence which is not guaranteed by current xserver. We will fix this issue
in next version. If you want

to try a full functional xserver with glamor, it’s recommended to use the
following xserver version:

commit a615b90cab7569fae9d123e4da1d3373c871d84b

Author: Keith Packard <keithp@keithp.com>

Date:   Wed Mar 14 11:32:36 2012 -0700

    Bump version number to 1.12.99.0

    Now that 1.12 has branched, reset the version on master to a

    development number.

            Signed-off-by: Keith Packard keithp@keithp.com

We have the following work items for next release:

1.       Fix the coexisting problem with glx for latest xserver. Don’t rely
on the module loading sequence.

2.       Continue performance tuning:

a)         Implement delay flushing mechanism to avoid tiny drawing
operation for each DrawElements/DrawArrays call.

b)         Implement atlas for small pixmap.

c)         Optimize trapezoid shader to reduce the overhead for those
non-edge pixels.

d)         Optimize trapezoid/gradient shader to merge the mask/source
creation and compositing into one shader.

e)         Optimize glamor itself’ overhead.

3.       Xv support.
