Functions
void	log_viewer_size_text (char *out, size_t n, uint64_t bytes)
	A file's size as the list and the DELETE question write it into out (n bytes): "300B", "4kB", "3.0MB" from 1MiB, "8.00GB" from 1GiB. The units are binary: 1kB is 1024 bytes, 1GB 1024^3.
void	log_viewer_row_text (const log_viewer_file_t *f, log_viewer_row_t *out)
	The texts of the list's row for f: its name, cut as FILES cuts a name; its time as FILES INFO writes it (files_time_text() of wall_local_s()), and nothing for none or a 1980 stamp; its size.
static void	render_question (gfx_canvas_t *c)
	Draws the DELETE question: the box, the file's name and size, CANCEL and DELETE.
static void	render_bar_of (gfx_canvas_t *c, int total, int visible, int scroll)
	Draw the scroll bar on BR_BAR.
static void	render_bar (gfx_canvas_t *c)
	Draw the browse list's scroll bar (render_bar_of()).
static void	empty_lines (char *why, size_t n, const char **hint)
	The empty list's two lines: why it is empty, and what the folder holds when it does not.
static void	render_browse (gfx_canvas_t *c)
	Draws the browse view: the tabs, the header, the file list with its scroll bar and the footer.
static const char *	conv_label (log_conv_t v)
	Returns the label of a number convention: an example of its format, or AUTO.
static void	render_import (gfx_canvas_t *c)
	Draws the import view: what was detected, the column list and the footer's buttons.
static void	draw_grid_band (gfx_canvas_t *band, int band_y0, int rows)
	Draws the plot's grid into the band of rows rows that starts at row band_y0.
static void	draw_trace_band (gfx_canvas_t *band, int k, int band_y0, int rows)
	Draws series k's trace into the band of rows rows that starts at row band_y0.
static int	cursor_x (void)
	Returns the pixel column of the cursor.
static void	render_plot (gfx_canvas_t *c)
	Draws the plot view: the summary, the series' chips, the traces in bands, the time axis and the footer.
static void	render_text (gfx_canvas_t *c)
	Draw the TEXT view: the report's rows in the browse list's panel, its name as the panel's title, the scroll bar and BACK.
void	lv_render (gfx_canvas_t *c, int buffer_index)
	Draws the view on screen into frame buffer buffer_index.
