The other sdl demo backends all use OpenGL, which defeats the
purpose of using SDL_Renderer for portabilty.
This is maybe not as good as a full SDL_Renderer backend, but it
is more flexible. For most applications software rendering of the
UI is more than fast enough.
I got a warning about this from my compiler (cl.exe). I tested it both ways, and the behavior is the same, except for the compiler warning no longer occurs after my change.
Fixes for the X11 backend with XFT fonts from demo/x11_xft:
- fixed some memory leaks by destroying XFT objects during cleanup
- the function to get text width was returning the wrong value
- the clipping space of text boxes was not implemented for XFT
- misc
- Be consistent about reading and writing pixel values to avoid casting/offset madness
- clean up function names for clarity/consistency
- Fix fence post errors preventing get/set pixels from operating on first row/column
- Enforce mutual exclusivity for pixel layout macros
If XftDrawString8() is given non-ASCII UTF-8 string it fails to properly render it.
Using XftDrawStringUtf8() instead seems to be doing the right thing.

The issue was introduced in the fix for 416 (commit 8559aeb).
The original problem was (backspace and arrows moving too fast) is not a
nuklear problem but a GLFW problem. Because of the way nuklear handles
input (it must be between input_begin and end), the key callback method
GLFW offers is not an option.
So we have to use glfwGetKey() which returns the current state of a key
not whether it was just pressed or released, so nuklear acts like it
was pressed every single frame, hence the "too fast" problem.
The fix checks for state change and discards the event if there was
no change. This kills key repeat behavior (for named keys) on
*all* platforms which makes deleting or arrowing inconvenient.
Since there's no way to fix the shortcomings of a callback vs event
based input API, my "fix" just makes the original fix conditional
on a macro NK_KEYSTATE_BASED_INPUT
