Hi all,
I'm implementing some optimizations to some cogl texture functions,
since they seem to have a considerable impact on my application
performance, and I've started with _cogl_texture_upload_to_gl() (GLES
backend).
I added some debugging statements in there, and it seems that the
texture is never sliced in my case.
So, I've implemented the optimization suggested by the FIXME comment,
that is avoid copying the bitmap to a temporary one. Things seem to work
fine, and definitely faster.
Before submitting this patch for review, though, I'd like to understand
whether the code blocks introduced by the "if ({x,y}_span->waste > 0)"
condition are also relevant in the single slice case, or if they can be
omitted. I left them out and I'm not noticing any problems.
Ciao,
Alberto
