wxOSX Retina fixes: wxImageList::GetSize().

wxImageList returns size of its bitmap as pixel size, i.e.  twice the
displayed screen on HiDPI screens.  Unfortunately,
wxImageList::GetSize() is used heavily in (generic) GUI drawing code,
e.g.  to properly size wxListCtrl's icon columns.  As wxImageList is
used primarily by controls, it seems reasonable to adjust for scaling
here, rather than requiring all users of the class to do it.

Remove wx/generic/colrdlgg.h from common GUI headers.

This header is not used in all ports, notably not in wxMSW nor wxGTK.

See #15753.

Use wxScopedArray instead of raw new[]/delete[] and fix memory leak.

Don't leak memory in case of error when reading from the stream in BMP loading
code.

Closes #15789.

Simplify and fix column determination code in wxGridStringTable.

The number of columns in the table is now (since r60717) stored in m_numCols,
so there is no need to get it from wxGrid any more. This is not only simpler
and faster but also more correct as the first row might not have the full
number of values yet.

Closes #15809.

Fix handling of bitmaps with alpha channel in wxMSW wxImageList.

Don't use mask and alpha together, this results in visual artefacts and masks
are unnecessary with RGBA bitmaps anyhow.

The only potentially problematic remaining case is mixing bitmaps with alpha
and mask inside the same image list (as we need to indicate whether we use the
mask or not when creating it), but this should probably be rare and in the
meanwhile we can at least RGBA bitmaps with image lists, which includes doing
this implicitly when they are used as button bitmaps.

Also refactor wxBitmap code to extract part of CopyFromIconOrCursor() to allow
reusing it in the newly added MSWUpdateAlpha().

See #11476.

Reduce the number of realloc() calls in wxHtmlTableCell.

Don't call realloc() after adding each row, this is horribly inefficient, so
preallocate more memory to avoid this.

Closes #15931.

Try to detect invalid wxHtmlWindow title format earlier.

Assert directly in wxHtmlWindow::SetRelatedFrame() instead of doing it much
later, hopefully people will read the comment at the assert point.

Support multiline strings in wxDC::DrawRotatedText() in wxMSW.

The native API doesn't support this, so do it by splitting the string into
lines manually.

Use automatic resource management in wxMSW wxDC::DrawRotatedText().

No real changes, just simplify the code by using RAII classes.

Recompute the tooltip width when changing its text in wxMSW.

Don't show windows with "hidden" XRC attribute at all.

This is better than showing them initially and then hiding them if only
because it avoids the unexpected wxEVT_SHOW events being generated.
