Geoffrey McRae 2901e7aec5 [client] egl: only upload the damage rects if they actually changed 
Profiling shows that a considerable amount of time is spent in
glBindBuffer and glBufferSubData when the damage rects are updated.
Since the amount of data here is quite small it's far faster to check if
it's different then to just blindly overwrite the buffer on each call.

Profiled on an Intel CPU with UHD P630 Graphics using magic-trace
