Subject: [PATCH 2/2] tests/util: smtpe: increase alpha to middle band
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The middle band is transparent for the ARGB1555 pixel format.
The alpha field of this format is coded on 1 bit, alpha colors field
(127) becomes 0 after application of the macro MAKE_RGBA.
I propose to modify the alpha colors to 128 (1 after application of
the MAKE_RGBA macro) to allow to visualize the band of the support
and little impact on the 16-bit color formats.
