e3095e0c1e Apply 3D transformations to gradient shaders.
This fixes only linear gradients. Sweep and radial gradients, as well as
bitmap shaders, will be fixed in a future commit.

ddb80bebb0 Add support for circular gradients to the GL renderer.
This change also adds full support for local transformation matrices on
sweep and radial gradients.

a5aed0d589 Add support for advanced blend modes with the framebuffer.
This adds the ability to blend with the framebuffer using Darken,
Lighten, Add, Multiply, Overlay and Screen.

7fbcc0492f Add support for paths.
Rendering is implementing by rasterizing the paths into A8 textures.
This cna be extremely inefficient if the path changes often.

06f96e2652 Refactor Skia shaders handling.
With this change, Skia shaders can easily be applied to any mesh. This change also
supports ComposeShader. For instance, this can be used to blend a gradient and a
bitmap togehter and paint a string of text with the result.

889f8d1403 Moved all the rendering code to the new shader generator.
The generator supports features that are not yet implement in the
renderer: color matrix, lighting, porterduff color blending and
composite shaders.

This change also adds support for repeated/mirrored non-power of 2
bitmap shaders.

ac670c0433 Generate shaders to cover all possible cases.
With this change, all the vertex and fragment shaders used by the GL
renderer are now generated based on a program description supplied
by the caller. This allows the renderer to generate a large number
of shaders without having to write all the possible combinations by
hand. The generated shaders are stored in a program cache.
