SDL library has an issue where it expects intrinsics headers to be
provided, but intrinsics are not exactly part of a standard, so there is
no guarantee that they will be available. As such, the library allows
you to turn them off. I am disabling them to allow for better
portability and ease of compilation.
I simplified a lot of API calls by pulling panel memory management
inside the library. All API calls which previously required a panel
as parameter are now handling their panel themself.
I removed the default vertex type and instead create an API to allow the
user to specify the vertex struct layout. Of course you are still
bound on what the library actual has on vertex data but the type and
sequence of the data is now configurable. This commit is quite
experiental and could introduce some bugs, but so far it look fine.
Nuklear now has three different property versions for int, float and
added by this commit a double version. Internally an additional change
happend. Now the type of the property is actually taken into account
and floating pointer errors due to casting are less of an issue.
Previously I packed standard library variable arguments as well as
file operation into one define `NK_INCLUDE_STANDARD_IO`. This caused
some problems and I split the define into two. So if you want the old
behavior you need to define `NK_INCLUDE_STANDARD_IO` as well as
`NK_INCLUDE_STANDARD_VARARGS`. If you only want file operations but
not variable arguments only define `NK_INCLUDE_STANDARD_IO` and
if you only want varargs but not file operations please only define
`NK_INCLUDE_STANDARD_VARARGS`.
Demos for x11 and sdl have been update so that `nk_xxx_handle_event'
return true (1) if the given event was usefull and processed by
nuklear and false (1) if not.
