Revert the change of r44514 and do hide the empty sizers. Code relying on them
being shown/positioned should use wxRESERVE_SPACE_EVEN_IF_HIDDEN flag but
assuming it by default results in completely unexpected layouts, e.g. still
using margins around a sizer with hidden window if it contains an empty
sub-sizer.
Closes#11426.

Make wxBoxSizer minimal size big enough to not only give each item enough
space to satisfy its minimal size but also to respect the proportions among
the items by default.

Sizer layout algorithm broke down if min size of an item happened to be -1,
i.e. the same value as we use as a sentinel for indicating that the min size
hasn't been fixed yet. It doesn't make much sense for min size to be negative
in the first place but currently this can happen at least for spacers so deal
with it here by ensuring that the min size we use is positive.
Closes#11842.

The new version of the algorithm tries to distribute the entire space
allocated to the sizer among its children, just as the version in 2.8 did,
while still respecting minimal children sizes first and foremost. This means
that the space allocated to the item will always be at least its minimal size
if the total space is at least equal to the sum of minimal sizes of the
children but that if there is enough space, the proportions will be respected
too.
Extended the unit test to check that laying out various combinations of three
elements results in the expected results.
Closes#11311.

This is similar to the previous commit but for the transversal direction of a
box sizer: we could give an item size larger than the size of the sizer itself
making only part of its window visible (and thus potentially making the window
unusable e.g. because the scrollbar wasn't visible at all).
Fix this by always restricting the item size in the minor direction to the
total size available and add a unit test which failed previously and passes
now.

After fixing the problem with "growing items by negative proportion" in r56010
(which still was the correct thing to do as it fixed such indefensibly broken
behaviour as shrinking items with larger proportion by more than "smaller"
items when there was not enough space) the items in a box sizer could become
larger than the total space allocated to the sizer resulting in only parts of
them being visible.
Fix this by truncating the items to the (remaining) total size even if this
means making them less than their minimal sizes -- because there is nothing
else we can do when the total space is smaller than the sum of minimal sizes
anyhow.
Closes#10008.

This allows to avoid problems with hiding all but the overridden overloads of
Insert() in wxSizer-derived classes, see #11616, without having to explicitly
write any using statements.
Keep Insert(size_t, wxSizerItem) virtual to allow the existing code overriding
it to keep working.

It used to add a spacer with the given size in both directions but this was
counter-intuitive and wasn't expected even by the original author of this code
so change it to behave more reasonably.

These functions return the number of columns or rows being currently used and
not 0, unlike the existing Get{Cols,Rows}(), if the corresponding number is
determined dynamically.

This commit is huge but there are no non-white-space changes in it.
Some files containing third-party sources (src/msw/wince/time.cpp,
src/x11/pango*.cpp) were left unchanged.

Confusing wxFlexGridSizer(int cols, int vgap = 0, int hgap = 0) was removed as
well as corresponding wxGridSizer ctor overload. New ctor overloads taking gap
as wxSize were added.
See #11040.
Closes#11091.

The old and confusing wxGridSizer(int cols, int vgap = 0, int hgap = 0) is removed and replaced with wxGridSizer(int cols, int vgap, int hgap).
New ctor overloads using wxSize for the gap parameter added.
