d6de89bebd Update SampleLua and lua files.
The lua files were moved at one point without the internal path
references being updated. This updates them so that the SampleLua slides
can be seen in their full glory.

8738cf4c19 ccpr: Simplify triangle corners
Modifies triangle corner shaders to just approximate their coverage with
linear values that ramp to zero at bloat vertices outside the triangle.

For the vertex backend, since corners now have the same fragment shader
as the rest of the triangle, we fold them in with the other steps and
draw triangles in a single pass.

The geometry backend still draws triangles in two passes, as there is
not an apparent performance advantage in combining them.

Updates SampleCCPRGeometry to better visualize this new geometry by
clearing to black and drawing with SkBlendMode::kPlus.

622650a194 ccpr: Simplify triangle corners
Modifies triangle corner shaders to just approximate their coverage with
linear values that ramp to zero at bloat vertices outside the triangle.

For the vertex backend, since corners now have the same fragment shader
as the rest of the triangle, we fold them in with the other steps and
draw triangles in a single pass.

The geometry backend still draws triangles in two passes, as there is
not an apparent performance advantage in combining them.

5183e649ef ccpr: Combine GS triangle hulls and edges into a single draw
Updates the geometry shader backend to match the vertex backend and draw
triangle rasters together with their their edges in a single draw call.
This gives a performance boost as well as cleaning up some API
awkwardness.

This is one step toward the final goal of drawing ccpr primitives in a single
pass.

cad0acf4db Fix thrashing issue with multitextured atlas.
To try to reduce memory usage, the atlas will look for space in
the earliest created pages and then invalidate plots in the latest
page to try to move those plots into an earlier one. The problem
was that the available space was not being evicted, so we kept loading
data back into the latest page.
