[cairo] Problems with gradients...

[benoit.vautrin at free.fr]

Hi ! 
 
Adapting a example code from David Reveman, I've made a simple test case which 
shows up some bugs in gradients patterns... 
 
http://benoit.vautrin.free.fr/gradient-scale.c 
 
Compile, execute and resize the window... 
 
1- Scaling problems: 
 
Gradients are scaled strangely (count the number of stripes when resizing...) 
but not on all paths... 
 
2- Proportions: 
 
When changing the width/heigh ratio, just transforming the gradient extend or 
vector or whatever you call it is not correct: 
Even if it is right when the ratio is the same as the original, it doesn't 
work in other cases... 
 
3- Image backend: 
 
Gradients are beautifull but from time to time don't fill the whole shape... 
 
There are other issues but I'm still trying to find simple test cases to show 
them. 
 
Bye,  
 
Ben.
