+ Comments on renderability of configs on various GL versions.
+ OpenGL < 3.0:
+ no built in support for render targets.
+ GL_EXT_framebuffer_object adds possible support for any sized format with base internal
+ format RGB, RGBA and NV float formats we don't use.
+ This is the following:
+ R3_G3_B2, RGB4, RGB5, RGB8, RGB10, RGB12, RGB16, RGBA2, RGBA4, RGB5_A1, RGBA8
+ RGB10_A2, RGBA12,RGBA16
+ Though, it is hard to believe the more obscure formats such as RGBA12 would work
+ since they aren't required by later standards and the driver can simply return
+ FRAMEBUFFER_UNSUPPORTED for anything it doesn't allow.
+ GL_ARB_framebuffer_object adds everything added by the EXT extension and additionally
+ any sized internal format with a base internal format of ALPHA, LUMINANCE,
+ LUMINANCE_ALPHA, INTENSITY, RED, and RG.
+ This adds a lot of additional renderable sized formats, including ALPHA8.
+ The GL_ARB_texture_rg brings in the RED and RG formats (8, 8I, 8UI, 16, 16I, 16UI,
+ 16F, 32I, 32UI, and 32F variants).
+ Again, the driver has an escape hatch via FRAMEBUFFER_UNSUPPORTED.
+
+ For both the above extensions we limit ourselves to those that are also required by
+ OpenGL 3.0.
+
+ OpenGL 3.0:
+ Any format with base internal format ALPHA, RED, RG, RGB or RGBA is "color-renderable"
+ but are not required to be supported as renderable textures/renderbuffer.
+ Required renderable color formats:
+ - RGBA32F, RGBA32I, RGBA32UI, RGBA16, RGBA16F, RGBA16I,
+ RGBA16UI, RGBA8, RGBA8I, RGBA8UI, SRGB8_ALPHA8, and
+ RGB10_A2.
+ - R11F_G11F_B10F.
+ - RG32F, RG32I, RG32UI, RG16, RG16F, RG16I, RG16UI, RG8, RG8I,
+ and RG8UI.
+ - R32F, R32I, R32UI, R16F, R16I, R16UI, R16, R8, R8I, and R8UI.
+ - ALPHA8
+
+ OpenGL 3.1, 3.2, 3.3
+ Same as 3.0 except ALPHA8 requires GL_ARB_compatibility/compatibility profile.
+ OpengGL 3.3, 4.0, 4.1
+ Adds RGB10_A2UI.
+ OpengGL 4.2
+ Adds
+ - RGB5_A1, RGBA4
+ - RGB565
+ OpenGL 4.4
+ Does away with the separate list and adds a column to the sized internal color format
+ table. However, no new formats become required color renderable.
+
+ ES 2.0
+ color renderable: RGBA4, RGB5_A1, RGB565
+ GL_EXT_texture_rg adds support for R8, RG5 as a color render target
+ GL_OES_rgb8_rgba8 adds support for RGB8 and RGBA8
+ GL_ARM_rgba8 adds support for RGBA8 (but not RGB8)
+ GL_EXT_texture_format_BGRA8888 does not add renderbuffer support
+ GL_CHROMIUM_renderbuffer_format_BGRA8888 adds BGRA8 as color-renderable
