Fix GL viewport sizing and ship a real playable default table

Browse Source 
The OpenGL back-buffer render target was created with the window's
logical/CSS size instead of its device-pixel size, so on any browser
tab with devicePixelRatio != 1 the GL viewport only covered a fraction
of the canvas's actual backing buffer (rendering anchored bottom-left,
matching GL's viewport origin) - confirmed against a live repro and
fixed to match the convention already used by the BGFX backend
elsewhere in the same file.

Also swap the bundled default table from test000-default-table.vpx
(upstream's rendering/component regression-test fixture, which has no
gameplay script) to exampleTable.vpx - a genuine playable demo table
with working flippers, slingshots, bumpers, targets and a plunger -
confirmed keyboard input and audio now work end-to-end through it.
