[PyOpenGL-Users] Upcoming fix may cause minor incompatibility...

[Mike C. F. <mcf...@ro...>]

I've just checked in changes on the 2.0.1 maintenance branch that fix a 
bug in how glDrawPixelsXX (that is, all glDrawPixels calls which take an 
array argument, rather than a string) operates.  The code was previously 
(unintentionally) reversing the first and second arguments, so that it 
would take (height,width) rather than (width,height) from the array to 
decide how to render it.

If you have any code that uses glDrawPixelsXX you will find that this 
fix causes your code to stop working.  Solution is simply to use 
properly-sized arrays (i.e. if you want an image 300x100 pixels wide 
it's shape should be (300,100,depth), rather than (100,300,depth)).  If 
you can't make that change, then simply assigning array.shape = 
(array.shape[1],array.shape[0]) + array.shape(2:])  will allow you to 
continue operating as before.

This bug does not affect string-based glDrawPixels calls.

Enjoy yourselves,
Mike
