GSoC project ideas for improving LOs core-code / performance

Hello,

I recently read through the list of GSoC project ideas for 2018, and
what made me wonder is that most project ideas center around small-mid
new features or new functionality.

Would it be also possible to work on projects, which improve the
current implementation.
There are e.g. a few long-standing performance problem with rendering
performance on Unix platforms:

https://bugs.documentfoundation.org/show_bug.cgi?id=80659
https://bugs.documentfoundation.org/show_bug.cgi?id=87485
https://bugs.documentfoundation.org/show_bug.cgi?id=115702
https://bugs.documentfoundation.org/show_bug.cgi?id=101162
......

The X11 backend has certain issues (e.g. reading back huge images via
XGetImage), the GTK3 backend performs all rendering via software and
the OpenGL backend on Linux lacks certain features which are crucial
to achieve acceptable performance (e.g. accelerated text rendering).

Such improvements would benefit all LIbreoffice' users on Unix platforms.
Would it be possible to get an item-point for profiling and improving
this situation on the project's idea page?

Thanks & best regards, Clemens
