We allow more time for students to work on the EasyHacks so you have the
time to study how to properly send the patch to gerrit. The deadline today
is only for the proposal.

That would be great - at least to get colibre_svg, breeze_svg and
elementary_svg packaged and provided to the users as an "experimental"
feature.

Yes, definitely.. for now. Our SVG rendering is not perfect so let's
do it step by step.

No. PNG by default then once we decide SVG is good enough, we get rid
of PNG and use SVG for everything.

That would just complicate things and prolong the status quo.

They are, but currently this is done by the icon designer.

Yes, when using OpenGL, scaling is done with shaders on the GPU
(that's not fixed function HW however.  It's a program - there is no
fixed function hardware for 3D anymore in modern GPU design).

Before I do that you should read [1]. Especially "Prove that you want
to get involved into LibreOffice" - where it says you should solve at
least one non-trivial easy hack. I didn't find any solved easy hacks
from you in our repository or in gerrit and you don't have much time
left so I suggest you hurry up.. after that we can discuss blurry
shadows.

That's a good start, however we use gerrit for submitting patches - see [1].

[1] https://wiki.documentfoundation.org/Development/GetInvolved

Also, we don't treat trivial easy hacks like this as enough to accept
a student for GSoC. The easy hack you solve must have some substance
so you can show us you can complete the GSoC task.

Blurry shadows focuses on making shadows blurry.

That's not how it works - at this period you should solve non-trivial
easy hacks, as this is a requirement for applying as a student. See
instructions how to apply at [1]. How to get started and how to get
the development environment set-up see [2].

It would be easier to use HSL colorspace instead of RGB. RGB is ideal
for monitors to produce a picture but not that good if you want to do
color manipulation. If you convert a RGB color to HSL colorspace you
have Hue - a 360 degree color value, Saturation of that color and
Lightness - how dark or light it is represented. This color
representation makes more sense and opens new possibilities. To get
the complementary color you just rotate the hue for 180°, adjacent
colors +-30°, desaturate a color, just lower the saturation...

So to make a set of colors you can just select some fixed saturation
and lightness values and then "rotate" the hue "wheel" and you get
your first set, then repeat.

What MS does with theme colors is tinting and shading, which is also
performed in HSL colorspace. Tinting means mixing the selected color
with white and shading is mixing with black (the value is in percent).
This is how they generate their palette, what I'm not sure exactly is
how they choose the mixing percentages.

You probably reinvented some transform color transform I guess.. but
it is an interesting approach too.

I have recently added support for sliders into VclBuilder so they map

it should be easy to put them into Sidebar now.
