All platform and renderbackend independent examples are now optional
demos for all platforms in `demo/`. Moving some demos from `example/`
provides an easier way to test GUI concepts for users and simplifies
maintenance.
All modifed state changed by the demo rendering functions is now set
to default values after being called. I tried to save and restore all
relavent state but for some reason function glBlendEquationSeperate
is not defined for me. So I decided to make it as easy as possible
for me and just set everything to default. This means you have to
either save and restore or reset your own OpenGL state after calling
`nk_xxx_render`. I know it is not perfect but I have no better
solution at this point in time.
Text manipulation in SDL1.2 is quite a pain to say the least. But
since this demo is already quite limited in some aspects I think it
is fine to just get things running. That being said if used seriously
then text input still needs some work.
I personally do not have a retina display, but I added some changes
to all `GLFW` demos/examples. If there are still issues please
report back to me what is not working correct (please test out clipping
by playing around with scrollbars as well)
Previously if you use `nk_edit_string` and use flag
`NK_EDIT_CLIPBOARD`, callbacks were not passed. I only tested it with
`nk_edit_buffer` and set the callbacks directly. This wrong behavior
is now fixed and should work copy & paste should behave correctly.
I passed a depth value inside `nk_xsurf_resize` and changed it to
default value. I tested it by removing the resizing code and it
worked for me again. Hopefully this fixes the bug.
Fixed window movement for windows without header and some small
wrong calculation inside the panel layout code. In addition I
added another example implementing a simple calculator.
