[GLES] Regression: Text background rendering broken - black rectangle instead of rectangle with rounded edges and transparency is drawn

[MC Return]

[Test Case]

1. Enable the shift-switcher and text plugins in CCSM
2. Open some windows
3. Start the shift switcher
   -> Make sure that the background text is drawn correctly

[Regression Potential]

Visual corruptions related to plugins using the text plugin.

Original description:

This bug is observable in several plug-ins drawing text like the Shift Switcher or Workspacenames for example.

[MC Return (mc-return)]

Investigation shows that the GL_BLEND function calls got lost in plugins/text/src/text.cpp with the big GLES merge, namely:

    wasBlend = glIsEnabled (GL_BLEND);
    if (!wasBlend)
 glEnable (GL_BLEND);

and later:

    if (!wasBlend)
 glDisable (GL_BLEND);

Probably this is the cause of the broken text rendering.
Investigating.
