254582aa35 OpenGL: Fix state tracking in situations with reused object handles 
If an OpenGL object is created, bound to a binding using the state
tracker, and then destroyed, a newly created object can be assigned the
same numeric handle by OpenGL. However, even though it is a new object,
and thus needs to be bound to the binding again, the state tracker
compared the current and previous handles and concluded that no change
needed to be made, leading to failure to bind objects in certain cases.

This manifested as broken text in VVVVVV, which this commit fixes along
with similar texturing problems in other games.

1fe9b0b82e VideoCore: Fix values of unset components in input attribute arrays 
If an input attribute array had a field with less than 4 components, the
remaining components were left unset if not specified by a default
vertex attribute. If neither mechanism would set a component, it would
assume a garbage value.

It has been verified that the hardware behavior is to instead to set the
missing components from the fixed default of (0 0 0 1). The default
vertex attribute values aren't used at all if a vertex array is
specified for that attribute.

Fixes UI graphics on Fire Emblem: Awakening, a small texturing glitch
when selecting a character in Cubic Ninja, as well as eliminating the
unset-W hack which was required for Ocarina of Time to not have
garbled triangles.

This change has been tested against hardware.

4e09202226 VideoCore: Saturate vertex colors before interpolating 
During testing, it was discovered that hardware does not interpolate
colors output by the vertex shader as-is. Rather, it drops the sign and
saturates the value to 1.0. This is done before interpolation, such that
(e.g.) interpolating outputs 1.5 and -0.5 is equivalent to as if the
shader had output the values 1.0 and 0.5 instead, with the interpolated
value never crossing 0.0.

This change has been tested against hardware.

e5c4fe0098 GL Renderer: Remove erroneous glEnable(GL_TEXTURE_2D) calls 
In OpenGL 3, texturing is always enabled, and this call is invalid.
While it produced no effect in the rest of the execution, it wouldn't
have the intended effect of disabling texturing for that unit. Instead
bind a null texture to the unit.

e4f5ec6272 Pica/VertexShader: Fix a bug caused due to incorrect assumptions of consecutive output register tables. 
We now write create a temporary buffer for output registers and copy all of them to the actual output vertex structure after the shader has run. This is technically not necessary, but it's easier to vectorize in the future.

It was trying to take the LSB from `coarse_x`, which would always be 0

too.

5961a2852d GSP: Update framebuffer info on all interrupts 
Hardware testing determined that the GSP processes shared memory
framebuffer update info even when no memory transfer or filling GX
commands are used. They are now updated on every interrupt, which isn't
confirmed correct but matches hardware behaviour more closely.

This also reverts the hack introduced in #404. It made a few games
behave better, but I believe it's incorrect and also breaks other games.
