2022-09-11Fix regression in fl_read_image() after introduction of hybrid Wayland/X11 ↵ManoloFLTK
platform. The special use context of fl_read_image() inside the draw() function of an Fl_Double_Window, where the function should read inside the window's double buffer rather than the on-screen window, no longer worked. Removal of all uses of the fl_window global variable from platform-independent code remains necessary, because this variable is ill-defined in the Wayland/X11 library.

2022-09-08Wayland: remove memory leak from missing wl_callback_destroy() call.ManoloFLTK
This hopefully corresponds to the memory leak mentioned in fltk.general named "FLTK and Wayland".
2022-09-08Add necessary virtual qualifier to ~Fl_Font_Descriptor() and derived.ManoloFLTK
2022-09-07Improve support of child windows that may leak outside their parent window.ManoloFLTK
1) add Wayland code that prevent subwindows from leaking outside their parent. This does not cover GL subwindows. 2) add macOS code that prevent GL subwindows from leaking outside their parent. This fixes issue #494 for the macOS platform. N.B.: Wayland GL subwindows are not prevented from leaking because no solution that would not require any change in client applications was found. Code that would cover Wayland GL subwindows but would require client applications to always use the FL_ALPHA flag is included in this commit in commented out form.
2022-09-06Wayland: fix memory leak on FL_KEYUP eventsAlbrecht Schlosser
The old code would allocate memory on FL_KEYDOWN and FL_KEYUP events and never free the latter. The fix is to allocate memory only on FL_KEYDOWN events which will be free'd later as intended. Also fix two unrelated whitespace errors.

2022-08-23Wayland: Fix obscure problem when closing file dialog under recent OS versions.ManoloFLTK
The problem is that the app sometimes stops after closing a file dialog window. It results in fact from a bug in function draw_title_bar of libdecor-gtk.c that erroneously calls libdecor_frame_set_max_content_size(). This bug is being proposed to be fixed by a MR to libdecor. But moving the libdecor_frame_set_min/max_content_size() calls after the capability changes hides the bug, and the problem with file dialog doesn't show.

2022-08-10Fix Fl_Xlib_Graphics_Driver for drawing tiled images.ManoloFLTK
Conflicting demands arise in the implementation of class Fl_Xlib_Graphics_Driver for drawing images with the XRender library : 1) Issue #163 leads to use a bilinear filter to draw-and-scale images. 2) This tends to blur the edges of drawn areas which is bad for tiled images (that is because the edges get alpha values, even for an opaque source image). This commit resolves the conflict adding a means to detect whether the library is busy drawing a tiled image. If so, the bilinear filter is not applied, drawn areas don't have blurred edges, resulting in a nice tiling. With this commit, these test apps perform correctly: - tiled_image is correct at all scaling factor values also when modified to use a depth-3 or a depth-4 Fl_RGB_Image as tile; - unittests - Drawing Images is correct at all scaling factor values; - pixmap_browser scales correctly up and down JPEG and PNG images.
