Reuse the windows code for this. Both versions had three parts: Enabling
the right menu items, adding the selection-specific ones, and showing the
menu. The second part is now common code, with the platform code in a new
function, since it grew big enough to be worth sharing.
In earlier versions, DrawPatternedCircle was a fairly complicated function.
Nowadays, it just copies pixels in memory, bounded by a circle. Since we
need to convert our surfaces to a format GTK+ can use anyway, combine that
step with the circle boundaries. Also use a cairo surface instead of a
GdkPixbuf. Cairo uses almost the same pixel format, except for
premultiplied alpha. Ignore this for now.
Specifically, GtkGrid. For most cases, this is an increase in lines of
code, but the landscape tools dialog can now be done with just three layout
widgets.
While at it, use a toolbar and move the mode buttons into it, too.
9e771ac moved the Win32 ClearInput implementation into SetInputFunctions,
but broke at least GTK while doing that. 9a7d57c0d2 fixed the assertion
failure in GTK that resulted, but failed to restore the removal of the old
completions.
Fix this by folding ClearInput into SetInputFunctions in all implementations.
The C++ standard library comes with perfectly fine implementations of
these functions, so there's no point in reimplementing them just for the
hell of it.
The minimum GTK version is now GTK+ 3.4, which is available since 2012.
It's part of Ubuntu LTS 12.04, and so should be available on any halfway
modern linux distribution.
This should allow getting rid of using deprecated GTK+ API much easier.
When switching dialogs in editor mode, the (paint) tools dialog wouldn't
be properly cleared, instead only destroying the dialog window. Thus,
the next time it would be used, it'd try painting onto a device context
which did no longer correspond to any existing window, which made OpenGL
sad.
It would be set by state and then immediately reset in Default(). This had the effect that if you used the color picker on sky before ever selecting a background material, the wrong background would be used.
Add a C4ShaderCall parameter to tho most important drawing functions, and
make C4DrawGL's CreateSpriteShader public with additional parameters to
specify additional defines and shader slices. C4Sky uses this to compile its
own shader with OC_SKY defined.
The new behaviour that allows 255 mat-tex combinations (once we increased
C4M_MaxTexCount...) is enabled with MapFg.bmp, and then MapBg.bmp can be
used to draw IFT or other fancy things.
