49582519c1 all: add a compiler directive kage:unit 
This change adds a new compiler directive 'kage:unit' to Kage. This
takes one of these two values: 'pixel' and 'texel'. The default value
is 'texel'.

With the pixel-unit mode, all the built-in functions treats pixels
instead of texels, and the texCoord argument of Fragment is in pixels.
This simplifies shader programs as programs no longer have the notion
of texels.

With the texel-unit mode, the behavior is the same as the current
behavior.

Closes #1431

81581df2b9 internal/graphicscommand: reland: add graphics.MaxVertexFloatCount and use it instead of IndicesCount 
This change is reland of 54e2790a06
but with a fix for WebGL. Also, this changes the logic when len(vertices)
exceeds the maximum: just remove the last part.

61f1d8b69f internal/graphics: remove the common vertices backend 
It was actually impossible to use the common vertices backend in a
thread-safe manner, and actually this caused race conditions.

This changes fixes the issue by giving up a central backend, and
letting images have their own vertices buffer.

Closes #2473

99e777b0c5 internal/atlas: do not adjust pixels for DrawTriangles(Shader) 
Adjusting pixels is needed to avoid strainge rendering to avoid unexpected
rendering (#1171). However, this adjustment caused unexpected holes
especially in a thick stroke.

This change moves the logic of adjusting pixels from atlas to
graphics.QuadVertices so that adjusting works only for DrawImage and
DrawRectShader.

26b9fa20c1 internal/graphics: Bug fix: Race condition at QuadVertices 
QuadVertices or verticesBackend.slice reused its backend slice.
This caused a race condition. QuadVertices can be accessed from
multiple goroutines, and resetting the head and copying the data
at internal/graphicscommand might not be synced.

This change fixes this issue by basically reverting
9cb631e30f.
