[cairo] Question regarding cairo-trace for map-to-image and unmap-image

[Dongyeon Kim]

Hello,

I have a working cairo sample that uses map-to-image to map gl surface to image surface, and unmaps afterwards.
I have created a trace file for the sample using cairo-trace, but when I try to run the trace file using cairo-perf-trace, I get the following error.

[  0]      egl   cairo_gl_map_to_image.5695 Error during replay, line 30: invalid value (typically too big) for the size of the input (surface, pattern, etc.)
[ # ]    image: pixman 0.26.0
[  0]    image   cairo_gl_map_to_image.5695 Error during replay, line 30: invalid value (typically too big) for the size of the input (surface, pattern, etc.)
[ # ]  image16: pixman 0.26.0
[  0]  image16   cairo_gl_map_to_image.5695 Error during replay, line 30: invalid value (typically too big) for the size of the input (surface, pattern, etc.)

It seems that when trying to run unmap-image from script it is not getting the right parameters.

Here is the full trace file: http://pastebin.com/eKCGquiG

Can anyone tell me how to resolve this problem?
