AquaTerm 1.1.1

[Mojca M. <moj...@gm...>]

Dear all,

I just wanted to let you know that AquaTerm 1.1.1 has been released.

The sources are available at
    https://github.com/AquaTerm/AquaTerm

Binaries can be downloaded from here:
    https://github.com/AquaTerm/AquaTerm/downloads
and support ppc/i386/x86_64 for Mac OS X 10.5 or later.

This is the first released version that properly works on 64-bit macs.
It supports transparency (it didn't support it in version 1.0.1, and
version 1.1.0 had two semi-serious problems). Gnuplot needs a patch to
make transparency work though:
-   AQUA_hasAlphaSupport = [AQTAdapter
respondsToSelector:@selector(setColorRed:green:blue:alpha:)];
+   AQUA_hasAlphaSupport = [adapter
respondsToSelector:@selector(setColorRed:green:blue:alpha:)];
or alternatively
AQUA_hasAlphaSupport = [AQTAdapter
instancesRespondToSelector:@selector(setColorRed:green:blue:alpha:)];


(The sourceforge page still needs to be updated to redirect to GitHub pages.)

Have you checked that this change works also for the earlier versions of aquaterm? 
Otherwise it needs to be wrapped in some version check.

This *is* the version check (or rather: feature check).

All the wrappers for transparency follow later. The problem is that
all wrappers assume that transparency is not supported based on the
result of this wrong check, and thus transparency is never used at
all.

New AquaTerm provides an instance method, but the line checks if a
class method exists. The result is thus "false" in both versions.

An alternative way would also be to do that check during configuration
and then replace

    if (AQUA_hasAlphaSupport)
      [adapter setColorRed:r green:g blue:b alpha:a];
    else
      [adapter setColorRed:r green:g blue:b];

by

    #ifdef HAS_AQUATERM_TRANSPARENCY
      [adapter setColorRed:r green:g blue:b alpha:a];
    #else
      [adapter setColorRed:r green:g blue:b];
    #endif

to avoid compiler warnings when old AquaTerm is used, but that's
probably too big hammer for a too tiny problem anyway (and compiler
warnings will go away once people upgrade aquaterm).
