We only need to wait for the fence before drawing to a buffer, not
before reading from it.
This might avoid hangs when re-allocating the fake front buffer, similar
to the previous change. But I haven't seen any evidence that this was
actually happening in practice.

We don't need to wait before drawing to the fake front buffer, as front
buffer rendering by definition is allowed to produce artifacts.
Fixes hangs in some cases when re-using the fake front buffer, due to it
still being busy (i.e. in use for presentation).

From Section 4.6.4 (Invariance and Linkage) of the GLSL ES 1.0 specification
"The invariance of varyings that are declared in both the vertex and
fragment shaders must match. For the built-in special variables,
gl_FragCoord can only be declared invariant if and only if
gl_Position is declared invariant. Similarly gl_PointCoord can only
be declared invariant if and only if gl_PointSize is declared
invariant. It is an error to declare gl_FrontFacing as invariant.
The invariance of gl_FrontFacing is the same as the invariance of
gl_Position."

Currently position is set before widgets are sized by gtk and
calculation can get wrong results where window is positioned
offscreen. Patch fixes this by setting aubfile window position
as 0,0 only when size_allocate has been called to the widget.
Now window is always positioned to 0,0 if imgui.ini is missing.

If we end up never taking the loop that writes ret, we can end up with
an uninitialized value, and if we're *really* unlucky, that value can
be -1, causing us to go down an error-path instead of a success path.
This was obviously not intended, so let's just initialize this to zero.

Gallium may pick L16A16_FLOAT to represent GL_INTENSITY16F if no intensity
format is provided by the driver. However, when calling
glGetTexLevelParameteriv(..., GL_TEXTURE_INTENSITY_SIZE, ...)
mesa will return a zero size because the actually used format has no
intensity channel and as a fallback only the sizes of the red/green
channels are checked.
Also checking for LA sizes in the allocated texture resolves this problem.
v2: Only check alpha channel size and return it (Marek)
L and A size are always the same in this case.
