I'm not in favor of making all those stubs public, at least for 1.3,
for these reasons:
- There would be two different ways in the API to do exactly
the same thing, fl_graphics_driver->xxx() and fl_xxx(),
a source of confusion.
- The Fl_Graphics_Driver API is smaller than the series of
fl_xxx() functions that deal with drawing, colors and fonts:
o some functions are independent from any graphics driver
(e.g., fl_color_average())
o others don't draw anything (e.g., fl_color(void))
o others are deliberately out of this API (e.g., fl_width()
because fonts are a very complex business already with the
display, so we don't multiply that to yet other devices)
so the ability to work with the fl_graphics_driver->xxx() calls
only is incomplete
- The full parallel use of two graphics contexts is not yet ready,
even with Mingodad's patch about STR #2535, because there remains
some global variables (e.g., fl_color_, the current color)
- Thus, there remains much work to hunt for these variables and
be sure not to forget any
- Switch between surfaces (and associated graphics drivers)
is very simple and fast:
my_surface->set_current()
But I agree there's much clutter of friend functions in the
Fl_Graphics_Driver class. And I'm ready to make them public
if it's deemed preferable.
What are the current plans for the full 1.3 release ?
