I'm taking a page from Dolphin's book, and including copies of each dependency's source code. This combines the ease of use of including pre-built libraries instead of needing to navigate a package manager - as is (or was) the case for MSVC - with the portability of using packages. Granted, this method's more of a jack of all trades, master of none, since it's *less* user-friendly than prebuilt packages (compilation times), and you don't get the per-distro compatibility fixes you'd get from a package manager. You can still use system libs if you want. In fact, it's still the default behaviour: compiling the libs manually is just a fallback. I'll add an option to force-enable this soon, however, since it's a nicer way to produce static MSYS2 builds than the hackish nightmare that I was using before. Not to mention, having my own copy of the sources means I can provide my own fixes and tweaks your package manager may not. For example, I can combine MSYS2's FreeType subpixel rendering with vcpkg's fix for SDL2 exporting its symbols in static builds.

/** Directs all graphics requests to an Fl_Image.
|
|
|
|
After creation of an Fl_Image_Surface object, call set_current() on it, and all subsequent graphics requests
|
|
will be recorded in the image. It's possible to draw widgets (using Fl_Image_Surface::draw())
|
|
or to use any of the \ref fl_drawings or the \ref fl_attributes.
|
|
Finally, call image() on the object to obtain a newly allocated Fl_RGB_Image object.
|
|
<br> Fl_GL_Window objects can be drawn in the image as well.
|
|
|
|
<br> Usage example:
|
|
\code
|
|
Fl_Widget *g = ...; // a widget you want to draw in an image
|
|
Fl_Image_Surface *img_surf = new Fl_Image_Surface(g->w(), g->h()); // create an Fl_Image_Surface object
|
|
img_surf->set_current(); // direct graphics requests to the image
|
|
fl_color(FL_WHITE); fl_rectf(0, 0, g->w(), g->h()); // draw a white background
|
|
img_surf->draw(g); // draw the g widget in the image
|
|
Fl_RGB_Image* image = img_surf->image(); // get the resulting image
|
|
delete img_surf; // delete the img_surf object
|
|
Fl_Display_Device::display_device()->set_current(); // direct graphics requests back to the display
|
|
\endcode
