2020-12-03Windows scaling: fix redraw after partial expose events.ManoloFLTK
Under XP (at least), WM_PAINT events occur where information of where to redraw is mostly given by the system, in the window's update region. When the GUI is scaled, that information must be un-scaled and then added to Fl_X::i(window)->region, for the adequate part of the window to be painted.
2020-12-02Remove build-time warning.ManoloFLTK
The warning message was: Makefile:318: warning: ignoring prerequisites on suffix rule definition

The change lets this function enlarge the size only when strictly necessary for image tiling.
2020-12-01Windows scaling: fix computation of border sizes.ManoloFLTK
The corrected error was to use, e.g., int dx = W - w->w() * s; which does not produce the desired integer value. The correct writing is : int dx = W - int(w->w() * s);

2020-11-24Improve resizing of test/cube demo (#157, #166)Albrecht Schlosser
Based on Greg's mods in 'cube-v5a-patch.txt' in this issue #157 comment: https://github.com/fltk/fltk/issues/157#issuecomment-732496554 Simplify the layout and keep border widths constant: - combine left GL window + buttons (ct_group) in left group (lt_grp) - make the cube Fl_Gl_Windows the resizable()s of their respective groups. The latter keeps the margin widths constant.

2020-11-20Fix for issue #159 - continuedManoloFLTK

2020-11-12Fix for issue #155 - continuedManoloFLTK
The issue lies in details how floating point scaled coordinates are converted to integer values and its impact on the drawing of large SVG images. This commit fixes the X11 platform. The macOS platform is immune because drawing uses floating point coordinates. The Windows platform still needs fixing.
