/* DRAW COMMAND QUEUE
/* COMMAND QUEUE
----------------------------
The command buffer API enqueues draw calls as commands in to a buffer and
therefore abstracts over drawing routines and enables defered drawing.

/* EDIT BOX
----------------------------
The Editbox is for text input with either a fixed or dynamically growing
buffer. It extends the basic functionality of basic input over `gui_edit`
and `gui_panel_edit` with basic copy and paste functionality and the possiblity
to use a extending buffer.
USAGE
----------------------------
The Editbox first needs to be initialized either with a fixed size
memory block or a allocator. After that it can be used by either the
`gui_editobx` or `gui_panel_editbox` function. In addition symbols can be
added and removed with either `gui_edit_box_add` and `gui_edit_box_remove`.
Widget function API
gui_edit_box_init() -- initialize a dynamically growing edit box
gui_edit_box_init_fixed() -- initialize a statically edit box
gui_edit_box_reset() -- resets the edit box back to the beginning
gui_edit_box_clear() -- frees all memory of a dynamic edit box
gui_edit_box_add() -- adds a symbol to the editbox
gui_edit_box_remove() -- removes a symbol from the editbox
gui_edit_box_get() -- returns the string inside the editbox
gui_edit_box_len() -- returns the length of the string inside the edditbox
