Could some of those approaches be used instead of our custom gradients?
I'm pretty sure Alec tried those when he was experimenting with
gradients, but unfortunately I don't know why he didn't choose them.
I'll ask him. Of course, it's always possible wx has improved since
Alec last played with gradients, so it may be worth experimenting again.
The GraphicsContext classes is new since Alec left, but if you're not
drawing the rest of the calendar using it then it won't be much help.
The wxDC gradient functions are newish as well, but the radial gradient
doesn't work on wxGTK.
Something else that is new that may help is we now have the ability to
get raw access to a wx.Bitmap's internal buffer. You can either use an
iterator interface to access the RGB(A) data, or there are some
convenience functions to create a wx.Bitmap from a buffer of RGB(A)
data, where the buffer can be anything that supports the Python buffer
interface, such as a string, array.array, or even a numpy array. The
latter can allow repeating patterns like gradients to be built fairly
fast. See the RawBitmapAccess sample in the wxPython demo for examples.
